VCC1_IC
Device supply voltage pin. The operative supply voltage is 12 V ± 10%.
Connect to 12 V_BUS and filter with RC network (R = 2.2 /0603 size, and
C=1x1 F MLCC capacitor vs. PGND).
39
LGATE1
Channel 1 LS driver output. Driver can support 12 V bus voltage.
A small series resistor helps in reducing device-dissipated power.
40
PHASE1
Channel 1 HS driver return path. Connected to the HS1 MOSFET source and
provides return path for the HS driver of channel 1.
41
PGND
Power ground pin (LS drivers return path). Connect to power ground plane.
Exposed pad connects also the silicon substrate. As a consequence it makes
a good thermal contact with the PCB to dissipate the power necessary to drive
the external MOSFETs. Connect it to the power ground plane using 4.2x4.2
mm square area on the PCB and with sixteen vias to improve electrical and
thermal conductivity.
