Function
Channel 2 LS Driver Supply.
It must be connected to others VCCDRx pins also when using 2-Phase
56 VCCDR2 Operation.
LS Driver supply can range from 5Vbus up to 12Vbus, filter with 1µF MLCC cap
vs. PGND2.
Channel 3 LS Driver Supply.
57
VCCDR3
It must be connected to others VCCDRx pins.
LS Driver supply can range from 5Vbus up to 12Vbus, filter with 1µF MLCC cap
vs. PGND3.
58
LGATE3
Channel 3 LS Driver Output.A small series resistor helps in reducing device-
dissipated power.
59 PGND3 Channel 3 LS Driver return path. Connect to Power ground Plane.
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.
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.
