## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | TEMP | input | Battery temperature sense input connected to the battery NTC; charging is suspended if TEMP is below 45% or above 80% of Vcc, and tying TEMP to GND disables the temperature check. |
| 2 | PROG | bidirectional | Charge-current program, monitor and shutdown pin: a 1% resistor to GND sets IBAT = (VPROG/RPROG) x 1000, the pin is regulated to 1V in constant-current mode, and it shuts charging down when it reaches 1.21V. |
| 3 | GND | power_in | Power ground for the charger. |
| 4 | VCC | power_in | Input supply for the charger, operating from 4.25V to 6.5V and requiring a bypass capacitor of at least 10uF. |
| 5 | BAT | power_out | Battery connection that supplies the charge current and regulates the final float voltage to 4.2V. |
| 6 | STDBY | output | Charge-complete indicator that is pulled low through an internal switch when the battery is fully charged, with a low output of 0.8V maximum at 2.5mA, and goes high-impedance otherwise. |
| 7 | CHRG | output | Open-drain charge-status output that is pulled low by an internal N-channel MOSFET during charging, with a low output of 0.8V maximum at 2.5mA, and is high-impedance otherwise. |
| 8 | CE | input | Chip enable input where a high level (above 1.2V) enables normal operation and a low level (below 0.6V) disables charging, and it can be driven by TTL or CMOS levels. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
