VCC1 (Input-side power supply pin) The VCC1 pin is a power supply pin on the input side. To suppress voltage fluctuations due to the driving current of the internal transformer, connect a bypass capacitor between the VCC1 and the GND1 pins. 3. GND1 (Input-side ground pin) The GND1 pin is a ground pin on the input side. 4. VCC2 (Output-side positive power supply pin) The VCC2 pin is a positive power supply pin on the output side. To reduce voltage fluctuations due to the driving current of the internal transformer and output current, connect a bypass capacitor between the VCC2 and the GND2 pins. 5. GND2 (Output-side ground pin) The GND2 pin is a ground pin on the output side. Connect the GND2 pin to the emitter / source of output device. 6. INA, DIS (Control input pin, input enabling signal input pin) They are pins for deciding the output logic. 7.

FET_G (MOS FET control pin for switching controller) This is a MOSFET control pin for the switching controller transformer drive. Leave it unconnected when the switching controller is not used. 14. SENSE (Connection to the current feedback resistor of the switching controller) This is a pin connected to the resistor of the switching controller current feedback. FET_G pin output duty is controlled by the voltage value of this pin. Connect it to VCC1 when switching controller is not used. 15. OUT(Output pin) The OUT pin is a gate driving pin. 16. OUT2 (Miller clamp pin) This is the miller clamp pin for preventing a rise of gate voltage due to miller current of output element connected to OUT1. OUT2 should be unconnected when miller clamp function is not used. 17. PROOUT (Soft turn-OFF pin) This is a pin for soft turn-OFF of output pin when short-circuit protection is in action. It also functions as a pin for monitoring gate voltage for miller clamp function and output state feedback function. 18. SCPIN1, SCPIN2, SCPIN3 (Short circuit current detection pin) These are the pins used to detect current for short circuit protection. When the SCPIN1 pin, SCPIN2 pin or SCPIN3 pin voltage exceeds the voltage set with the VSCDET parameter, the SCP function will be activated, this will make the IC function in an open state. To avoid such trouble, connect a resistor between the SCPIN and the GND2 or short the SCPIN pin to GND2 when the SCP function is not used. 19. TC (Resistor connection pin for setting constant current source output) The TC pin is a resistor connection pin for setting the constant current output. If an arbitrary resistance value is connected between TC and GND2, it is possible to set the constant current value output from TO. 20. TO1, TO2 (Constant current output / sensor voltage input pin) The TO1 pin and the TO2 pin are constant current output / voltage input pins. It can be used as a sensor input by connecting an element with arbitrary impedance between TOx pin and GND. Furthermore, the TOx pin disconnect detection function is built-in. 21. UVLOIN (Output-side UVLO setting input pin) The UVLOIN pin is a pin for deciding UVLO setting value of VCC2. The threshold value of UVLO can be set by dividing the resistance voltage of VCC2 and inputting such value. www.rohm.com © 2013 ROHM Co., Ltd. All rights reserved.

Under voltage Lockout (UVLO) function The BM60051FV-C incorporates the under voltage lockout (UVLO) function on V_BATT, VCC1 and VCC2. When the power supply voltage drops to the UVLO ON voltage, the OUT pin and the FLT pin will both output the “L” signal. When the power supply voltage rises to the UVLO OFF voltage, these pins will be reset. However, during the fault output holding time set in “Fault status output” section, the OUT pin and the FLT pin will hold the “L” signal.

Short circuit protection (SCP) function When the SCPIN pin voltage exceeds a voltage set with the VSCDET parameter, the SCP function will be activated. When the SCP function is activated, the OUT pin voltage will be set to the “Hi-Z” level and the PROOUT pin voltage will go to the “L” level first (soft turn-OFF).Next, when the short-circuit current falls below the threshold value and after tSCPOFF has passed, OUT pin and PROOUT pin become L.

Temperature monitor function Constant current is supplied from TOx pins from the built-in constant current circuit. This current value can be adjusted in accordance with the resistance value connected between TC and GND2. Furthermore, TOX pin has voltage input function, and outputs signal of TOx pin voltage converted to Duty from SENSOR pin. When voltage of either one of TOX pins is no less than disconnect detection voltage VTOH, SENSOR pin outputs L. Therefore, when only one of the TOX pins is used, connect a resistor between the other TO pins and GND2 to keep pin voltage at no more than VTOH.

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 terminals. 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. The absolute maximum rating of the Pd stated in this specification is when the IC is mounted on a 70mm x 70mm x 1.6mm glass epoxy board. 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. Rush 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. www.rohm.com © 2013 ROHM Co., Ltd.

Unused Input Terminals Input terminals 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 terminals should be connected to the power supply or ground line. 12. 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. www.rohm.com © 2013 ROHM Co., Ltd.
