PIN FUNCTIONS

Pin #

Name

Description

1

IN1

Control inputs. IN1 and IN2 have internal pull-down resistors.

24

IN2

2, 3,

16, 17

GND

System ground connection.

4

nSLEEP

Sleep mode input. Set nSLEEP to logic low to enter low-power sleep mode. nSLEEP

has an internal pull-down resistor.

5, 20,

21, 22

NC

No connection.

6, 7

OUT1

Output terminal 1.

8

ISET

Current programming resistor. Connect a resistor from ISET to ground to set the

current limit and VISEN output voltage.

9, 10, 11

VIN

Input supply voltage. Decouple VIN to GND with a ceramic capacitor

≥100nF to

GND.

12, 13

OUT2

Output terminal 2.

14

CPA

Charge pump flying capacitor. Connect a 100nF ceramic capacitor between CPA

and CPB.

15

CPB

18

VCP

Charge pump output. Connect a 100nF capacitor from VCP to VIN.

19

VISEN

Current sense output voltage.

23

nFAULT

Fault indication. nFAULT is an open-drain output. nFAULT is at logic low when in a

fault condition (OCP, OTP, OVP).

EP

GND

Exposed pad. The exposed pad must be connected to ground.
