Pin Description

1

ENB

Inhibit pin (high active ): By driving this pin low, all outputs can be turned off regardless of input

signals. Built-in pull-down resistor (100 kΩ typ.).

2

This pin sets the oscillation frequency for the charge pump drive.

Connect a 62 kΩ (typ.) resistor.

3

IN1

Input pin: it controls the power MOSFET connected to UU. Built-in pull-down resistor

(100 kΩ typ.).

4

IN2

Input pin: it controls the power MOSFET connected to VU. Built-in pull-down resistor

(100 kΩ typ.).

5

IN3

Input pin: it controls the power MOSFET connected to WU. Built-in pull-down resistor

(100 kΩ typ.).

6

IN4

Input pin: it controls the power MOSFET connected to UB. Built-in pull-down resistor

(100 kΩ typ.).

7

IN5

Input pin: it controls the power MOSFET connected to VB. Built-in pull-down resistor

(100 kΩ typ.).

8

IN6

Input pin: it controls the power MOSFET connected to WB. Built-in pull-down resistor

(100 kΩ typ.).

9

SGND1

Signal block GND pin: shared internally with pin 11.

10

CP1

Capacitor pin for charge pump.

11

SGND2

Signal block GND pin: shared internally with pin 9.

12

CP2

Capacitor pin for charge pump.

13

Power supply pin: when under-voltage (5.5 V typ.) is detected, FAULT output goes high. On this

occasion, all outputs are switching normally, and charge pump circuit does not come to a stop.

14

FAULT

Diagnosis output pin: when under-voltage (5.5 V typ.) is detected, FAULT output goes high.

High-side/low-side arm shorting mode, FAULT output goes high and all outputs are shut down.

Circuit configuration is N-ch open drain.

15

WB

Drives the power MOSFET connected to the low side of the W phase.

16

PGND1

Power block GND pin: shared internally with pin 18.

17

VB

Drives the power MOSFET connected to the low side of the V phase.

18

PGND2

Power block GND pin: shared internally with pin 16.

19

UB

Drives the power MOSFET connected to the low side of the U phase.

20

UU

Drives the power MOSFET connected to the high side of the U phase.

21

VU

Drives the power MOSFET connected to the high side of the V phase.

22

WU

Drives the power MOSFET connected to the high side of the W phase.

23

CPV

Final stage capacitor pin for the charge pump.

24

This pin sets the oscillation frequency for the charge pump drive.

Connect a 270pF (typ.) capacitor.
