Application Note 1896 Author: Richard Garcia HIP2103, HIP2104 Evaluation Board User’s Guide Introduction The HIP2103_4MBEVAL1Z is an evaluation tool for the HIP2103 and HIP2104 half bridge MOSFET drivers. This tool consists of a mother board and HIP2103DBEVAL1Z and HIP2104DBEVAL1Z evaluation daughter cards. The mother board platform provides an on-board microcontroller that is used to generate appropriate control inputs to the HIP2103 or HIP2104. The frequency, the PWM duty cycle, and the dead-time provided by the microcontroller are user adjustable. The 6 position DIP switch is used to setup the PWM switching frequency (positions 1, 2, and 3) and the dead-time (positions 4, 5, and 6). One specific combination of DIP switch settings (all positions set to on) disables the signals from the microcontroller and enables all of the external inputs. For those customers who would like to modify the firmware of the PIC18F2431 microcontroller, an RJ25 connector is provided for easy connection with Microchip firmware development tools (not provided or supported by Intersil). For customers who desire to provide their own external signals, the on-board controller can be configured to allow the daughter cards to be controlled by externally provided inputs. VCC and VDD on/off (HIP2104 only) DEAD FREQ TIME The daughter cards can also be used as stand-alone units mounted on a customer designed main board that incorporates customer selected bridge FETs and any other external circuits desired. The daughter cards have optional circuits so that the HIP2103 or HIP2104 can be configured as required by the customer’s application.

Application Note 1896 Block Diagram application. The jumper strap option, J2, is used to select the appropriate bias source labeled VCC from the HIP2104 or 5V from an external bias connected to 5V and GND on TB8. Optional external LI, HI, VCen, and Vden Inputs Push buttons An external 12V bias is not required for the HIP2104 daughter card because VDD is provided internally by the HIP2104 driver. LEDs MicroController and Associated Circuits Microcontroller Option switches Ext. Bias The 12V bias for the HIP2103 daughter card must be supplied by an external source connected to VDD and GND of TB6. External Inputs Buffer VCen, Vden, LI, HI, Multiplexer HIP2103 or HIP2104 Daughter Card Turning the potentiometer, R1, fully counter clockwise (CCW) reduces the duty cycle of the output of the bridge to a minimum. Turning fully clockwise results with a maximum duty cycle. The duty cycle is proportional to the tap voltage of the potentiometer independent of the PWM frequency. The dead-time subtracts from the duty cycle period on the leading edge of the HI and LI inputs to the daughter cards altering the actual duty cycle. Half Bridge FETs To emulate controllers that may to be used by customers that do not have the ability to generate dead-time, the dead-time of the microcontroller can be set to zero. On the daughter cards, an optional RCD circuit is provided for the LI and HI inputs of the HIP2103, HIP2104 to generate dead-time. Jumper Option 3.3V 12V Optional DC Motor or other Loads FIGURE 2. HIP2103_4MBEVAL1Z, BLOCK DIAGRAM The HIP2103_4 evaluation board is a fully self contained test platform to evaluation the HIP2103 or the HIP2104 which are provided on daughter cards. Evaluation Board Application The HIP2103_4MBEVAL1Z mother board and associated daughter cards are the same test boards as used by the Intersil application engineers and I.C. designers to evaluate the performance of the HIP2103 and HIP2104 MOSFET drivers. Bias Supplies The HIP2103_4MBEVAL1Z mother board requires a current limited lab supply (0V to 50V) for the VBAT and GND inputs on TB1. The current capacity is dependant on the users desired load if any. An external 3.3V to 5V bias supply (~25mA) is required for the microcontroller and associated circuits. Alternatively, the VCC output of the HIP2104 daughter card can be used to provide the 3.3V bias for the microcontroller as intended in a real 2 The PWM frequency and the dead-time options of the microcontroller are configured by the SW5 DIP switch. Refer to the chart on the mother board schematic (page 9) for the DIP switch settings or to Table 1. The DIP switch settings are read only once after the Start/Stop button is pressed to start the PWM. Any changes to the frequency or dead-time settings are not recognized until the PWM is stopped then re-started. Be cautious if the zero dead-time option is selected when the HIP2103, HIP2104 daughter cards are not configured for delays with the RCD circuit as this will result with shoot-thru currents in the bridge. Four LEDs are used to indicate the operating status of the microcontroller. Refer to the Setup and Operating Instructions section for complete details. Half Bridge The bridge is composed of two (SiR662DP) 60A, 60V, MOSFETs. Each FET has an optional gate to source and drain to gate capacitors to allow the emulation of FETs with larger capacitances if desired. An optional series gate resistor is also provided for each bridge FET that can also be used the emulate the internal gate resistance. The current rating of these SiR662DP MOSFETs was chosen primarily to eliminate the need of a heat sink when operating with heavy current loads. The maximum output load current is constrained by the current rating of the VBAT (TB1) and the Vout (TB7) terminal blocks. If a load current higher than 15A is desired, it is recommended that the battery and load wires are soldered directly to the solder pads of the TB1 and TB2 terminal blocks on the bottom of the PCB. The bridge bias source is connected to the GND_VBAT terminal block (TB1). The voltage source can be either a current limited power supply (recommended for initial setup) or a battery (a fuse is highly recommended). An external load can be connected to the GND_VOUT (TB7) terminal block. The load can be of any configuration (for example AN1896.0 November 13, 2013 Application Note 1896 a DC motor or an LCR load) as desired by the user within the constraints of the bridge FETs and the terminal blocks. R23 0 D1 SW4 1 2 1 VCEN SWITCH The HIP2104 has integrated LDOs for the VDD bias of the driver and VCC for the bias of the controller. VDD and VCC outputs of the HIP2104 are available on the GND_VDD_VCC terminal block (TB6). External loads on the LDOs can be connected here.

DIODE TO SUPPRESS LI-ON BATTERY RIPPLE When using the HIP2103 daughter card, both VDD and VCC must come from external sources. The same terminal block used for the LDO outputs of the HIP2104 can be used as external inputs when using the HIP2103. • Gate to source resistors on the bridge FETs. (R19 and R21 are omitted) As mentioned previously, the J2 strap option is used to select the bias source for the microcontroller. If the 5V strap option is selected, the bias to the microcontroller will always be present (if the external source is on) even when the LDO outputs of the HIP2104 are not enabled. This is desirable during the initial setup of the evaluation board or when testing the HIP2103. • Gate to source, and gate to drain capacitor on the bridge FETs (C11, C12, C9, and C10 omitted). The capacitors can be added to emulate larger FETs. Three push buttons provide control signals to the microcontroller. As usual, the reset button restarts the firmware. The Start/Stop button starts and stops the PWM signals to the LI and HI inputs of the HIP2103, HIP2104. The Sleep button turns on and off the sleep mode. User Assembly Options The following user optional assembly features are provided on the evaluation mother board: • Series connected diode (D1) on the VBAT input to the HIP2104 daughter card for holding up VBAT when there is severe ripple voltage from a LI-ON battery.

These two signals are provided by two mechanical switches, SW2 and SW3. Mechanical switches are used to demonstrate the intended use of the VCEN and VCEN inputs of the HIP2104 although digital logic signals can also be used when external inputs are optionally chosen. The debouncing feature of the VDCEN and VDEN inputs can also be observed when using the mechanical switches. Note that either of these two switches can be turned on or off randomly to demonstrate the performance of the HIP2104 when either of the LDO outputs are turned off during operation of the bridge.

VCEN AND VDEN DAMPENING RESISTORS FIGURE 6. BYPASS DIODES (D1, D2) USED FOR DEAD TIME GENERATION • The HS pin has an RC filter (R7/C7 on the HIP2103 daughter card and R7/C9 on the HIP2104 daughter card) that was required for early engineering samples (rev. A) of the HIP2103/4. This filter is not necessary for the production grade parts. The default value for R7 is zero ohms and the capacitor between HS and VSS is omitted. A similar transient situation may occur with the HS pin. In this situation, a ringing spike can be more severe because of high speed switching from the bridge FETs, the large amplitude of switching currents, and because of parasitic inductance associated with the bridge high current PCB traces. Because the amplitude of the ringing spike also increases with the switching load current amplitude, evaluation should be over the full operating load range including fault currents. Good bridge circuit PCB design will minimize but cannot totally eliminate ringing on the HS node. These switching transients are relatively fast. When evaluating the spikes on these pins, it is necessary to use a time base on the scope of about 100ns/division. Slower sweep speeds may mask the switching spike depending on the sample rate of the digital scope. 4 AN1896.0 November 13, 2013 Application Note 1896 Other methods can also be used to reduce ringing on the HS node. Sufficiently large value gate resistors on the bridge FETs will reduce the switching speed and consequently the amplitude of the ringing. The above mentioned RC filter on the HS pin can also be used to attenuate the spike directly on the HS pin. By default, the gate resistors on the HIP2103/4 daughter cards, R5 and R6, is 24.9Ω. With this evaluation PCB layout, 24.9Ω is sufficient to prevent excessive switching transient but a customer’s PCB layout may require more or less gate resistance or another method to attenuate the switching transients. Another source of switching transients that must be dealt with is from the bridge voltage source, especially with LI-ON batteries. When the LI_ON battery load current is interrupted when the bridge turns off, the voltage from the battery can rise dramatically because of the internal inductance of the battery. The usual solution is to have sufficiently large capacitance across the bridge. This bridge bypass capacitor is effectively an LC filter working with the internal inductance of the LI-ON battery (typically a few hundred nH). If the capacitor value is large enough, the battery voltage will be close to the nominal unloaded value with minimal ripple. Another approach to reduce the amplitude of the voltage transient from the battery without increasing the size or value of the bridge capacitor is to increase the PWM switching frequency. If it is not desirable to use relatively large value capacitors across the bridge, a clamping method must be used to limit the peak voltage ripple from the battery. In any case, a relatively small capacitor across the bridge should be used to limit the rate of change of the ripple voltage and to minimize the effects of the PCB parasitic trace inductance on the HS pin. Another consequence of allowing a relatively large ripple voltage on the battery is that under heavy load conditions, the voltage ripple valley will drop to very low levels. Because most motor loads respond to the average voltage applied, this ripple voltage is of minimal concern. The problem is that if the valley voltage drops too low, the 12V LDO (VDD) of the HIP2104 will sag resulting with a lower gate drive voltage. The UVLO of the HIP2103/4 is 4.5V (or optionally 7.5V). If the bridge FETs are selected appropriately, this low gate drive voltage will have not significant effect except for the usual consequence of higher rDS(ON) of the bridge FETs. To mitigate this problem of excessively low ripple voltage from the battery, a diode in series with the VBAT input of the HIP2104 daughter card with a capacitor to ground will hold up the voltage on VBAT (and consequently the VCC and VDD outputs) when the valley voltage is low (Figure 3). This series connected diode is an assembly option on the HIP2103_4MBEVAL1Z mother board. The default configuration has a zero ohm resistor in parallel with the diode. Setup and Operating Instructions The follow procedure ensures a correct setup of the evaluation board and illustrates various operating methods. Required Lab Equipment • Power supply (or battery), 13V minimum to 50V maximum operating for the bridge bias. The current rating of the power supply must have sufficient capacity for the external load used 5 for testing (if any). If no load is applied, 200mA is sufficient. If a battery is the power source, it is highly recommended that an appropriate fuse be used. With a LI-ON battery, it is necessary to add sufficient capacitance (100µF or greater) across the VBAT terminal block to prevent excessive ringing. • Bias supply, 12V at ~50mA, require for testing the HIP2103 • Bias supply, 3.3V to 5.0V at ~50mA, for testing the HIP2103 • Bench fan (only necessary when testing with large loads at elevated ambient temperatures) • Four channel oscilloscope, ~500MHz recommended • Current Probe (optional) when testing with external loads. • Multimeter Initial Configuration for the Microcontroller The following procedure illustrates how to configure the microcontroller without applying power to the bridge. 1. Connect a 5.0V bias supply to the +5V_GND terminal block (TB8). This voltage powers the microcontroller. 2. Ensure that the jumper strap on J2 is on the 5V option. This will connect the microcontroller to the external lab supply. 3. Setup the DIP switch on the mother board with the desired PWM frequency and dead-time. For the initial setup, start with 20kHz and 400ns dead-time (in bold type). TABLE 1.

AN1896.0 November 13, 2013 Application Note 1896 5. Turn the duty cycle potentiometer, R1, fully counter clockwise until it clicks. 6. Turn on the lab supply. Observe that the four LEDs turn on and off, one after another. This flashing sequence indicates that power has been applied. After the initial flash, all LEDs will be off. led3 led2 led1 led0 At initial turn on, leds will turn on and off one at a time starting with led0 7. Observe that the LI and HI inputs are low. 8. Press the Start/Stop push button once. The RUN LED (led0) will blink indicating that PWM signals from the controller have been enabled. EXERNAL led3 led2 SLEEP RUN led1 led0 With PWM signals present on LI and HI, the RUN LED is blinking The DIP switch options are read only when the Start/Stop button is pressed to start the PWM signals. Changing the settings while the RUN LED is flashing will have no effect. To update the DIP switch setting, change the setting, stop the PWM signals, then start again. 9. Slowly rotate the potentiometer, R1, to the right (CW) until the following waveforms appear. Initial Setup to Evaluate the HIP2104 Daughter Card The following procedure illustrates how to setup the daughter cards and applying power to the bridge. 1. Install a HIP2104 daughter card on the mother board. Be careful with the polarity. Incorrect installation may damage the daughter card and the mother board. 2. Connect an additional scope probe to the HS test point on the mother board. Set the vertical gain to 10V/Div and the time base to 10µs/Div. 3. Ensure that the VDEN and VCEN switches are off. 4. Connect the bridge power supply to the VBAT_GND terminal block (TB1). 5. Starting with an initial output of 20V, and a current limit of 200mA, turn on the bridge supply. Caution: If a Li-on battery is used instead of a regulated supply, it is recommended to add a 100uF or larger capacitor across the VBAT input terminal. This is necessary because the relatively large inductance of an Li-on battery may resonate with the bridge bypass capacitor resulting with excessive voltage. 6. Turn on the VDEN switch. 7. Measure 12V +/5% on the VDD pin of TB6 relative to the GND pin. 8. Turn on the VCEN switch. 9. Measure 3.3V ±3% on the VCC pin of TB6 relative to the GND pin. 10. Press the Start/Stop button. led0 is flashing. 11. Turn the potentiometer CW until the following waveform appears: 10. Confirm that a 400ns dead-time is present. 11. Rotate the potentiometer CCW to zero the PWM period. 12. Press the Start/Stop push button to disable the PWM outputs. The blinking led0 will turn off. 13. Press the Sleep button. led1 will turn on to indicate that the sleep mode is active. 14. Press the Start/Stop button. led0 will flash indicating that the PWM outputs are active. Simultaneously, led1 will turn off indicating that the sleep mode is no longer active. 15. Press the Sleep button. led0 will turn off and led1 will turn on indicating that the sleep mode is active. 12. Confirm that the PWM frequency is 20kHz. 13. Turn off VCEN and VDEN switches. The HS output will stop switching. 14. Turn off the bridge supply 15. Move the J2 jumper from the 5V strap to the VCC strap. This configures the microcontroller to be powered from the VCC output of the HIP2104. 16. Turn on the bridge supply (still at 20V). 6 AN1896.0 November 13, 2013 Application Note 1896 17. Turn on the VCEN switch. All 4 LEDs will flash one after another indicating power has been applied to the controller. 18. Press the Start/Stop button. The LI and HI inputs will start switching. (The HS output is not switching because VDD is off) 19. Turn on the VDen switch. HS is again switching.

TB6 is an output terminal for VCC and VDD when testing the HIP2104 but it is also an input terminal for VDD bias for the HIP2103. VCC on TB6 can also be used as a bias input for the microcontroller (or alternatively TB8).
