Pin description (continued)
Not internally connected.
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.
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.
Channel 3 LS driver output. A small series resistor helps in reducing device-
dissipated power.
Channel 3 LS driver return path. Connect to power ground plane.
Channel 1 LS driver return path. Connect to power ground plane.
Channel 1 LS driver output. A small series resistor helps in reducing device-
dissipated power.
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.
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.
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.
