Function

Channel 1 HS driver output.

1 UGATE1

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

Channel 1 HS driver supply.

2

BOOT1 Connect through a capacitor (100 nF 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.

Channel 3 HS driver output.

5 UGATE3

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

Channel 3 HS driver supply.

6

BOOT3 Connect through a capacitor (100 nF 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 (100 nF 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.

11

N.C. Not internally connected.

12

N.C. Not internally connected.

13

N.C. Not internally connected.

14

N.C. Not internally connected.

15

VCC

Device supply voltage. The operative voltage is 12 V ±15 %. Filter with 1 µF

(typ) MLCC vs. SGND.

PHASE_ Phase selection pin. Internally pulled up by 12.5 µA(typ) to 5 V.

16

SEL

It allows selecting between 2 phase and 3 phase operation. See Table 11 for

details.
