Name

Type

Description

1

VIN

PWR

Input voltage, connect a 0.1

μF or greater ceramic capacitor from IN to GND

as close to the device as possible

2

DM_OUT

Input/Output

D- data line to USB host controller

3

DP_OUT

Input/Output

D+ data line to USB host controller

4

ILIM_SEL

Input

Logic level input signal used to dynamically change power switch cur-

rent-limit threshold; logic LOW selects ILIM_L, logic HIGH selects ILIM_H

5

EN

Input

Logic level control input for turning the power switch and the signal switches

on/off.

When EN is LOW, the device is disabled, the signal and power switches

are OFF.

6

CTL1

Input

Logic level control inputs for controlling the charging mode and the signal

switches. The “000” configuration is used to force and discharge of the

output (VOUT) capacitor.

7

CTL2

Input

8

CTL3

Input

9

NC

NC

No Connect. Open or connect to Ground

10

DP_IN

Input/Output

D+ data line to connector, input/output used for hand-shaking with portable

equipment

11

DM_IN

Input/Output

D- data line to connector, input/output used for hand-shaking with portable

equipment

12

VOUT

PWR

Power switch output

13

FAULT#

Output

Active low open drain output, asserted during over-temperature or cur-

rent-limit conditions

14

GND

GND

Ground

15

ILIM_L

Input

External resistor used to set current-limit threshold when ILIM_SEL is LOW.

See current limit setting in detailed description.

16

ILIM_H

Input

External resistor used to set current-limit threshold when ILIM_SEL is

HIGH. See current limit setting in detailed description.

17

Thermal Pad

GND

Ground
