Function

1

UGATE1

Channel 1 HS driver output.

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

Channel 1 HS driver supply.

2

BOOT1

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.

Channel 3 HS driver return path.

4 PHASE3 It must be connected to the HS3 MOSFET source and provides return path for

the HS driver of channel 3.

5

UGATE3

Channel 3 HS driver output.

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

Channel 3 HS driver supply.

6

BOOT3

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.

Channel 2 HS driver return path.

8 PHASE2 It must be connected to the HS2 MOSFET source and provides return path for

the HS driver of channel 2.Leave floating when using 2 Phase operation.

Channel 2 HS driver output.

9 UGATE2 A small series resistors helps in reducing device-dissipated power.

Leave floating when using 2 Phase operation.

Channel 2 HS driver supply.

10

BOOT2

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.Leave floating when using 2 Phase operation.

VCC

Device Supply Voltage. The operative voltage is 12V ±15%. Filter with 1µF (typ)

MLCC vs. SGND.

PHASE_ PHASE SELection Pin.Internally pulled up by 12.5µA(typ) to 5V.

16

It allows selecting between 2 Phase and 3 Phase operation.See Table 10 for

details.

OUTput ENable Pin.Internally pulled up by 12.5µA(typ) to 5V.

Forced low, the device stops operations with all MOSFETs OFF: all the

OUTEN

protections are disabled except for Preliminary over voltage.

Leave floating, the device starts-up implementing soft-start up to the selected

VID code.

Cycle this pin to recover latch from protections; filter with 1nF (typ) vs. SGND.
