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.

N.C.

Not internally connected.

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.

N.C.

Not internally connected.

PHASE2

Channel 2 HS driver return path.

It must be connected to the HS2 mosfet source and provides return path for the

HS driver of channel 2.

9UGATE2

Channel 2 HS driver output.

A small series resistors helps in reducing device-dissipated power.

BOOT2

Channel 2 HS driver supply.

Connect through a capacitor (100nF typ.) to PHASE2 and provide necessary

Bootstrap diode.

A small resistor in series to the boot diode helps in reducing Boot capacitor

overcharge.

N.C.

Not internally connected.

PHASE4

Channel 4 HS driver return path.

It must be connected to the HS4 mosfet source and provides return path for the

HS driver of channel 4.

UGATE4

Channel 4 HS driver output.

A small series resistors helps in reducing device-dissipated power.

BOOT4

Channel 4 HS driver supply.

Connect through a capacitor (100nF typ.) to PHASE4 and provide necessary

Bootstrap diode.

A small resistor in series to the boot diode helps in reducing Boot capacitor

overcharge.
