5

LVG (1)

1. The circuit guarantees less than 1 V on the LVG and HVG pins (at Isink = 10 mA), with VCC > 3 V. This

allows omitting the “bleeder” resistor connected between the gate and the source of the external MOSFET

normally used to hold the pin low.

O

Low-side driver output

OUT

P

High-side (floating) common voltage
