Function
1UGATE1
Channel 1 HS driver output.
A small series resistors helps in reducing device-dissipated power.
2BOOT1
Channel 1 HS driver supply.
Connect through a capacitor (100nF typ.) to PHASE1 and provide necessary
Bootstrap diode.
A small resistor in series to the boot diode helps in reducing Boot capacitor
overcharge.
3
N.C.
Not internally connected.
4
PHASE3
Channel 3 HS driver return path.
It must be connected to the HS3 mosfet source and provides return path for the
HS driver of channel 3.
5UGATE3
Channel 3 HS driver output.
A small series resistors helps in reducing device-dissipated power.
6BOOT3
Channel 3 HS driver supply.
Connect through a capacitor (100nF typ.) to PHASE3 and provide necessary
Bootstrap diode.
A small resistor in series to the boot diode helps in reducing Boot capacitor
overcharge.
7
N.C.
Not internally connected.
8
PHASE2
