VCCDR2

Channel 2 LS driver supply.

It must be connected to others VCCDRx pins also when using 2-phase

operation.

LS driver supply can range from 5 Vbus up to 12 Vbus, filter with 1 µF MLCC

cap vs. PGND2.

VCCDR3

Channel 3 LS driver supply.

It must be connected to others VCCDRx pins.

LS driver supply can range from 5 Vbus up to 12 Vbus, filter with 1 µF MLCC

cap vs. PGND3.

LGATE3

Channel 3 LS driver output. A small series resistor helps in reducing device-

dissipated power.

PGND3

Channel 3 LS driver return path. Connect to power ground plane.

PGND1

Channel 1 LS driver return path. Connect to power ground plane.

LGATE1

Channel 1 LS driver output. A small series resistor helps in reducing device-

dissipated power.

VCCDR1

Channel 1 LS driver supply.

It must be connected to others VCCDRx pins.

LS driver supply can range from 5 Vbus up to 12 Vbus, filter with 1 µF MLCC

cap vs. PGND1.

PHASE1

Channel 1 HS driver return path.

It must be connected to the HS1 MOSFET source and provides return path for

the HS driver of channel 1.

N.C.

Not internally connected.

PAD

Thermal

pad

Thermal pad connects the silicon substrate and makes good thermal contact

with the PCB to dissipate the power necessary to drive the external MOSFETs.

Connect to the PGND plane with several VIAs to improve thermal conductivity.
