PRODUCTION DATA.
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. |
