PIN FUNCTIONS

Pin #

Name

Description

1

VIN

Input supply voltage. Bypass to ground with a ceramic capacitor.

Additional bulk

capacitance may be required. See Applications Information section.

2

CPA

Charge pump capacitor.

Connect a ceramic capacitor between these pins. See

Applications Information section.

3

CPB

4

VREG

Gate drive supply output. Connect a ceramic capacitor to ground. See Applications

Information section.

5

BSTA

Bootstrap phase A. Connect a ceramic capacitor to SHA.

See Applications Information section.

6

SHA

High-side source connection phase A.

7

GHA

High-side gate drive phase A.

8

GLA

Low-side gate drive phase A.

9, 10,

11, 12

NC

No connection. Leave these pins open.

13

BSTB

Bootstrap phase B. Connect a ceramic capacitor to SHB.

See Applications Information section.

14

SHB

High-side source connection phase B.

15

GHB

High-side gate drive phase B.

16

GLB

Low-side gate drive phase B.

17

LSS

Low-side source connection.

18

PWMB

PWM input pin for phase B. High drives phase B high; low drives phase B low.

Internal pulldown.

19

GND

Ground.

20

PWMA

PWM input pin for phase A. High drives phase A high; low drives phase A low.

Internal pulldown.

21

ENB

Enable pin for phase B. Active high enables the gate driver for phase B; low disables

the gate driver for phase B. Internal pulldown..

22

GND

Ground.

23

ENA

Enable pin for phase A. Active high enables the gate driver for phase A; low disables

the gate driver for phase A. Internal pulldown.

24

nFAULT

Fault indication. Open-drain output. nFAULT is logic low when in a fault condition.

25

nSLEEP

Sleep mode input. Logic low to enter low-power sleep mode; high to enable. Internal

pulldown.

26

OCREF

Over-current protection reference voltage input.

27

DT

Dead time setting.

Connect a resistor to ground to set the dead time.

See

Applications Information section.

28

GND

Ground.
