Pin 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 current-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 current-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.
