Function

60 PGND1 Channel 1 LS Driver return path. Connect to Power ground Plane.

61

LGATE1

Channel 1 LS Driver Output.A small series resistor helps in reducing device-

dissipated power.

Channel 1 LS Driver Supply.

62 VCCDR1 It must be connected to others VCCDRx pins.

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

vs. PGND1.

Channel 1 HS driver return path.

63 PHASE1 It must be connected to the HS1 mosfet source and provides return path for the

HS driver of channel 1.

64

N.C. Not internally connected.

Thermal pad connects the Silicon substrate and makes good thermal contact

PAD

THERMAL with the PCB to dissipate the power necessary to drive the external mosfets.

PAD

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