NCP81155 Datasheet (ON Semiconductor)

NCP81155, MOSFET Driver

Pin No.

Symbol 1 BST 2 PWM 3 EN 4 VCC 5 DRVL 6 GND 7 SW 8 DRVH 9 FLAG Description Floating bootstrap supply pin for high side gate driver.

Connect the bootstrap capacitor between this pin and the SW pin.

Control input: PWM = High * DRVH is high, DRVL is low.

PWM = Low * DRVH
