Pin Functions
| PIN | TYPE(1) | DESCRIPTION | |
|---|---|---|---|
| NO. | NAME | ||
| 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 Table 3. Can be tied directly to IN or GND without pullup or pulldown resistor. |
| 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. Can be tied directly to IN or GND without pullup or pulldown resistor. |
| 6 | CTL1 | I | Logic-level inputs used to control the charging mode and the signal switches; see Table 3. Can be tied directly to IN or GND without pullup or pulldown resistor. |
| 7 | CTL2 | I | |
| 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 overtemperature or current limit conditions. |
| 14 | GND | P | Ground connection. |
| 15 | ILIM_LO | I | External resistor connection 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 connection used to set the high-current-limit threshold. |
| — | Thermal Pad | — | Internally connected to GND; used to heatsink the part to the circuit board traces. Connect to GND plane. |
(1) G = ground, I = input, O = output, P = power.
