Name
Function
1SGND
All the internal references are referred to this pin. Connect to the PCB Signal
Ground.
2VCC
Device Power Supply and LS driver supply.
Operative voltage is 12V ±15%. Filter with at least 1
F MLCC vs. ground.
3LGATE1
Channel 1 LS Driver Output.
A small series resistor helps in reducing device-dissipated power.
4
PGND
LS Drivers return path. Connect to Power ground Plane.
5LGATE2
Channel 2 LS Driver Output.
A small series resistor helps in reducing device-dissipated power.
6LGATE3
Channel 3 LS Driver Output.
A small series resistor helps in reducing device-dissipated power.
7
BOOT1
Channel 1 HS driver supply.
Connect through a capacitor (100nF typ.) to PHASE1 and provide necessary
Bootstrap diode.
A small series resistor upstream the boot diode helps in reducing Boot capacitor
overcharge.
8UGATE1
Channel 1 HS driver output.
A small series resistors helps in reducing device-dissipated power.
9
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.
