DESCRIPTION
1 IN P Input voltage and supply voltage; connect 0.1 μF or greater ceramic capacitor from IN to GND as close
to the device as possible
2 DM_OUT I/O D– data line to USB host controller
3 DP_OUT I/O D+ data line to USB host controller
4 ILIM_SEL I Logic-level input signal used to control the charging mode, current limit threshold, and load detection;
see the control truth table
5 EN I Logic-level input for turning the power switch and the signal switches on/off; logic low turns off the signal
and power switches and holds OUT in discharge.
6 CTL1 I
7 CTL2 I Logic-level inputs used to control the charging mode and the signal switches; see the control truth table
8 CTL3 I
9 STATUS O Active-low open-drain output, asserted in load detection conditions
10 DP_IN I/O D+ data line to downstream connector
11 DM_IN I/O D– data line to downstream connector
12 OUT P Power-switch output
13 FAULT O Active-low open-drain output, asserted during over-temperature or current limit conditions
14 GND P Ground connection
15 ILIM_LO I External resistor used to set the low current-limit threshold and the load detection current threshold. A
resistor to ILIM_LO is optional; see Current-Limit Settings in DETAILED DESCRIPTION.
16 ILIM_HI I External resistor used to set the high current-limit threshold
NA PowerPAD Internally connected to GND; used to heat-sink the part to the circuit board traces. Connect to GND
plane.
