Pin Functions

PIN TYPE(1) DESCRIPTION
NAME NO.
CS 4 O Active-low, open-drain output. When OUT current is more than approximately half of the current limit set by a resistor on ILIM_SET pin, the output is active low. Maximum sink current is 10 mA.
DM 7 I/O Connected to the D– or D+ line of USB connector. Provide the correct voltage with an attached portable equipment for DCP detection, high impedance while disabled.
DP 6 I/O Connected to the D+ or D– line of USB connector. Provide the correct voltage with an attached portable equipment for DCP detection, high impedance while disabled.
EN 5 I Logic-level control input. When it is high, turns power switch on, when it is low, turns power switch off and turns DP and DM into the high impedance state.
GND 1 G Ground connection.
ILIM_SET 2 I External resistor used to set current limiting Threshold. TI recommends 16.9 kΩ ≤ RILIM_SET ≤ 750 kΩ.
IN 3 P Power supply input voltage connected to the power switch. Connect a ceramic capacitor with a value of 0.1-µF or greater from the IN pin to GND as close to the device as possible.
OUT 8 O Power-switch output. Connect to VBUS of USB
PowerPAD PowerPAD G Ground connection.
(1) G = Ground, I = Input, O = Output, P = Power
