Pre-driver block Transmitter (Tx) includes inverter circuits to input AC electricity into both ends of the primary coil and to produce the electromotive force on the secondary side by electromagnetic induction. BD57020MWV includes two pre-driver blocks to support Half Bridge inverter and Full Bridge inverter configurations. For the Half Bridge inverter configuration, it is necessary to set the pre-driver 1 (PWM0 signal). For the Full Bridge inverter configuration, it is necessary to set the pre-driver 1 and pre-driver 2 (PWM1 signal). The output power control modes are the frequency control, the duty control and the phase control. The pre-driver block prevents a through current by monitoring the on/off timing of low side FET and high side FET. For high efficiency, the bootstrap drive system which sets the H side-L side to Nch FET is adopted. It is necessary to put a capacitor (0.1 – 0.47 µF) between the BOOT1 (BOOT2) terminal and the SW1 (SW2) terminal to maintain the voltage potential between these pins. Install a ceramic capacitor as close to these pins as possible. 2. Digital Ping Tx inputs AC electricity into the primary coil and by electromagnetic induction develops an electromotive force on the secondary coil which starts the Receiver (Rx). This phase is called Digital Ping. Tx keeps transmitting power as long as it receives Digital Ping from the Rx. Tx controls the transmission power based on a packet including the power incoming information from Rx. The following registers are used to configure Digital Ping. (1) PWM0PRD: Setting register for the period of PWM0 signal This register is used to set the period of PWM0 signal. The PWM0 signal sets the period of the pulse to be output from pre-driver 1 with a count level. The relation between the period of PWM0 signal and source clock is determined by the following formula: SourceCloc k 1 PWM 0 PRD round TargetClock “round” means rounding off to the nearest whole number For example, if source clock=32MHz and target clock=100kHz, PWM0PRD register is set to the following value: 32000 PWM 0 PRD round 1 319 0x013F 100 Name PWM0 PRDL PWM0 PRDH Address 0x20 0x21 b7 b6 b5 b4 b3 b2 b1 b0 PWM0 PRD7 PWM0 PRD15 PWM0 PRD6 PWM0 PRD14 PWM0 PRD5 PWM0 PRD13 PWM0 PRD4 PWM0 PRD12 PWM0 PRD3 PWM0 PRD11 PWM0 PRD2 PWM0 PRD10 PWM0 PRD1 PWM0 PRD9 PWM0 PRD0 PWM0 PRD8 Initial Value R/W 0x00 R/W 0x00 R/W After PWM0DTYH (0x23) is written, this register is updated with the new data. (2) PWM0DTY: Setting register for the duty of PWM0 signal This register is used to set the duty of PWM0 signal. PWM0 signal is the output signal at pre-driver 1. The duty of PWM0 signal is set with the count number of the source clock. After this register has been written, when the counter number of PWM0 signal becomes 0, the data of PWM0PRD register and PWM0DTY register are updated with the new data. The relation between the duty of PWM0 signal and source clock is determined by the following formula: Duty PWM 0 DTY int PWM 0 PRD 1 100 “int” means rounding down to the nearest whole number For example, if source clock= 32MHz and target clock=100kHz with duty=50%, PWM0DTY register is set to the following value: 50 PWM 0 DTY int 320 1 160 0x00A0 100 www.rohm.com © 2015 ROHM Co., Ltd.

PWM1 signal is a signal with the same period and duty as PWM0 signal. After PWM0DTYH register (0x23) is written and the counter number of PWM0PRD register becomes 0, the data of this register is updated with the new data. The enable range of this register is from 0x0001 to (PWM0PRD). PWM1 signal will not be generated if the PWM1PHS register is set to a value greater than or equal to the value in PWM0PRD register.

By setting the power mode bit (PWMD0, PWMD1), the operation mode is changed. The operation mode is Digital Ping when PWMD=0x0. Meanwhile, the operation mode is Analog Ping, which is also the low power consumption mode, when PWMD=0x1. On the other hand, the operation is Stop Mode when PWMD=0x3. During Stop Mode, all blocks are stopped. BD57020MWV uses the input clock signal from TCXOIN terminal for source clock of the internal movement. Please set this register with TCXSEL = 1, and connect TCXO with frequency between 32 to 52MHz to TCXOIN terminal.

Analog Ping BD57020MWV outputs pulse signal from primary coil to detect if Rx was put on the interface of the Tx. The presence of Rx is confirmed if BD57020MWV detects a change in the coil current or voltage. When the change of the coil current or voltage reaches the threshold value of the Analog Ping detection, the state shifts to Digital Ping. Additionally, BD57020MWV will generate an interrupt after Analog Ping executes a set number of times. In Analog Ping, it is necessary to drive a primary coil near the resonant frequency. The setting of the frequency is performed right before an output of Analog Ping, like Digital Ping. Set the following registers to configure Analog Ping. (1) APGCTRL: Control register for Analog Ping This register is used to set the start and stop of Analog Ping and the expected value of Rx detection by Analog Ping. BD57020MWV starts Analog Ping when APEN=1 is set. The period and duty of PWM0 should be set before APEN is set to 1. BD57020MWV stops Analog Ping when APEN=0 is set. When the state of the COIL_IN terminal is matched with the expected value of this register, BD57020MWV detects Rx. When APEN is 1, BD57020MWV becomes the stand-by state, the circuit electric current decreases.BD57020MWV will execute Analog ping until any of the two conditions is met: 1.) Analog Ping finishes the set number of repeated execution without detecting any Rx. 2.) Rx is detected wherein it generates an interrupt and stops Analog Ping. The expected value of Analog Ping is configured as follows: ・[7] APEN: Control bit for Analog Ping (0x1: Enable 0x0：Disable) ・[6:2] Reserved ・[1:0] APEX0, APEX1: Expected value of Analog ping (0x1: Detect the Rx 0x0: Not detect the Rx 0x2, 0x3: Reserved) Name APGCTRL Address 0x16 b7 b6 b5 b4 b3 b2 b1 b0 APEN *1 *1 *1 *1 *1 APEX1 APEX0 - - - - - Initial Value 0x00 R/W R/W *1 prohibition against writing (2)APGSTT: Analog Ping status register This register shows status of Analog Ping. www.rohm.com © 2015 ROHM Co., Ltd.

AM demodulator block BD57020MWV has the two AM demodulator blocks for communication with Rx. The characteristics of demodulator blocks are different to improve communication stability. The following registers are used for the configuration of the demodulator blocks. (1) RXCTRL: Control register for Packet reception This register is used to control the demodulating blocks. If PRE1 bit=1, the demodulator 1 is enabled to receive the packets. If PRE2 bit=1, the demodulator 2 is enabled to receive the packets. It is possible to set both PRE1 bit and PRE2 bit to 1 at the same time, then demodulator 1 and demodulator 2 works independently. The digital filters of the demodulators are enabled if FTE1 bit and FTE2 bit are set to 1 in this register. In order to raise communication stability, please be sure that the digital filters are enabled. If other demodulating circuit is receiving a packet even if reception error (frame error, parity error or check sum error) occurs in demodulating circuit 1 or demodulating circuit 2 while CTRL is 0, it does not generate an interrupt. If CTRL bit = 1 and a reception error occurs on demodulator 1 or demodulator 2, BD57020MWV generates an interrupt signal immediately. ・[7] CTRL: Setting bit of exclusive control function ・[6] Reserved ・[5] FTE2: Setting bit for the digital filter of the demodulator 2 ・[4] FTE1: Setting bit for the digital filter of the demodulator 1 ・[3:2] Reserved ・[1] PRE2: Setting bit for the demodulator 2 ・[0] PRE1: Setting bit for the demodulator 1 Name RXCTRL Address 0x01 b7 b6 CTRL *1 - b5 FTE2 b4 b3 b2 b1 b0 FTE1 *1 *1 PRE2 PRE1 - - Initial Value 0x00 R/W R/W *1 prohibition against writing (2) RXSTT: Packet reception status register This register holds the status of the packet reception of the demodulating circuit.

Reverse Connection of Power Supply Connecting the power supply in reverse polarity can damage the IC. Take precautions against reverse polarity when connecting the power supply, such as mounting an external diode between the power supply and the IC’s power supply pins. 2. Power Supply Lines Design the PCB layout pattern to provide low impedance supply lines. Separate the ground and supply lines of the digital and analog blocks to prevent noise in the ground and supply lines of the digital block from affecting the analog block. Furthermore, connect a capacitor to ground at all power supply pins. Consider the effect of temperature and aging on the capacitance value when using electrolytic capacitors. 3. Ground Voltage Ensure that no pins are at a voltage below that of the ground pin at any time, even during transient condition. 4. Ground Wiring Pattern When using both small-signal and large-current ground traces, the two ground traces should be routed separately but connected to a single ground at the reference point of the application board to avoid fluctuations in the small-signal ground caused by large currents. Also ensure that the ground traces of external components do not cause variations on the ground voltage. The ground lines must be as short and thick as possible to reduce line impedance. 5. Thermal Consideration Should by any chance the power dissipation rating be exceeded the rise in temperature of the chip may result in deterioration of the properties of the chip. In case of exceeding this absolute maximum rating, increase the board size and copper area to prevent exceeding the Pd rating. 6. Recommended Operating Conditions These conditions represent a range within which the expected characteristics of the IC can be approximately obtained. The electrical characteristics are guaranteed under the conditions of each parameter. 7. Inrush Current When power is first supplied to the IC, it is possible that the internal logic may be unstable and inrush current may flow instantaneously due to the internal powering sequence and delays, especially if the IC has more than one power supply. Therefore, give special consideration to power coupling capacitance, power wiring, width of ground wiring, and routing of connections. 8. Operation Under Strong Electromagnetic Field Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction. 9. Testing on Application Boards When testing the IC on an application board, connecting a capacitor directly to a low-impedance output pin may subject the IC to stress. Always discharge capacitors completely after each process or step. The IC’s power supply should always be turned off completely before connecting or removing it from the test setup during the inspection process. To prevent damage from static discharge, ground the IC during assembly and use similar precautions during transport and storage. 10. Inter-pin Short and Mounting Errors Ensure that the direction and position are correct when mounting the IC on the PCB. Incorrect mounting may result in damaging the IC. Avoid nearby pins being shorted to each other especially to ground, power supply and output pin. Inter-pin shorts could be due to many reasons such as metal particles, water droplets (in very humid environment) and unintentional solder bridge deposited in between pins during assembly to name a few. 11. Unused Input Pins Input pins of an IC are often connected to the gate of a MOS transistor. The gate has extremely high impedance and extremely low capacitance. If left unconnected, the electric field from the outside can easily charge it. The small charge acquired in this way is enough to produce a significant effect on the conduction through the transistor and cause unexpected operation of the IC. So unless otherwise specified, unused input pins should be connected to the power supply or ground line. www.rohm.com © 2015 ROHM Co., Ltd. All rights reserved.

Regarding the Input Pin of the IC This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them isolated. P-N junctions are formed at the intersection of the P layers with the N layers of other elements, creating a parasitic diode or transistor. For example (refer to figure below): When GND > Pin A and GND > Pin B, the P-N junction operates as a parasitic diode. When GND > Pin B, the P-N junction operates as a parasitic transistor. Parasitic diodes inevitably occur in the structure of the IC. The operation of parasitic diodes can result in mutual interference among circuits, operational faults, or physical damage. Therefore, conditions that cause these diodes to operate, such as applying a voltage lower than the GND voltage to an input pin (and thus to the P substrate) should be avoided.

Example of monolithic IC structure 13. Ceramic Capacitor When using a ceramic capacitor, determine the dielectric constant considering the change of capacitance with temperature and the decrease in nominal capacitance due to DC bias and others. 14. Area of Safe Operation (ASO) Operate the IC such that the output voltage, output current, and power dissipation are all within the Area of Safe Operation (ASO). 15. Thermal Shutdown Circuit(TSD) This IC has a built-in thermal shutdown circuit that prevents heat damage to the IC. Normal operation should always be within the IC’s power dissipation rating. If however the rating is exceeded for a continued period, the junction temperature (Tj) will rise which will activate the TSD circuit that will turn OFF all output pins. When the Tj falls below the TSD threshold, the circuits are automatically restored to normal operation. Note that the TSD circuit operates in a situation that exceeds the absolute maximum ratings and therefore, under no circumstances, should the TSD circuit be used in a set design or for any purpose other than protecting the IC from heat damage. 16. Over Current Protection Circuit (OCP) This IC incorporates an integrated overcurrent protection circuit that is activated when the load is shorted. This protection circuit is effective in preventing damage due to sudden and unexpected incidents. However, the IC should not be used in applications characterized by continuous operation or transitioning of the protection circuit. www.rohm.com © 2015 ROHM Co., Ltd. All rights reserved.
