NAME

FUNCTION

24

PHASE1

Switch Node for Channel 1. Connect this pin to the source of high-side MOSFET and the drain of

the low-side MOSFET. This pin is used as sink for UGATT1 driver. This pin is also monitored by

the adaptive shoot-through protection circuitry to determine when the high-side MOSFET has

turned off. An Schottky diode between this pin and the ground is recommended to reduce

negative transient voltage, which is common in a power supply system.

25

PGND

Power Ground for the low-side gate drivers. Connect this pin to the source of low-side MOSFETs.

This pin is used as sink for LGATE1 and LGATE2 drivers.
