Functional Pin Description
Pin No.
1,
11 (Exposed Pad)
2
Pin Name
GND
DRVOUT
Pin Function
Ground. The exposed pad must be soldered to a large PCB and connected to
GND for maximum power dissipation.
IGBT Driver Output Pin.
3
VDD
Power Input Pin.
4
DRVIN
IGBT Driver Input Pin.
Charge Enable Pin. The charge function is executed when CHARGE pin is
5
CHARGE set from Low to High. The chip is in Shutdown mode when CHARGE pin is
set to Low.
6
STAT
Charge Status Output. Open Drain output. When target output voltage is
reached, N-MOSFET turns on. This pin needs a pull up resistor.
7
FB
Feedback Voltage Pin.
8
CS
Input Current Setting Pin.
9
NC
No Internal Connection.
10
SW
N-MOSFET Switching Node.
