PIN FUNCTIONS
TYPE ⁽¹⁾
DESCRIPTION
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.
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.
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.
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.
G Ground connection.
I
External resistor used to set current-limiting threshold, recommended 16.9 kΩ ≤ R_{ILIM_SET} ≤ 750 kΩ.
P
Power supply. Input voltage connected to 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.
O Power-switch output. Connect to VBUS of USB
G Ground connection.
