VSET pin is used to program the device regulation voltage at end-of-charge using a ±1% pulldown resistor. The available pulldown resistor and corresponding charging levels are listed in the following table.
| RESISTOR | CHARGE VOLTAGE (V) |
|---|---|
| > 150kΩ | No charge (open-circuit) |
| 100kΩ | 1-cell LiFePO4: 3.50V |
| 82.5kΩ | 1-cell LiFePO4: 3.60V |
| 61.9kΩ | 1-cell LiFePO4: 3.70V |
| 47.5kΩ | 1-cell Li-Ion: 4.05V |
| 35.7kΩ | 1-cell Li-Ion: 4.58V |
| 27.4kΩ | 1-cell Li-Ion: 4.53V |
| 24.3kΩ | 1-cell Li-Ion: 4.35V |
| 18.2kΩ | 1-cell Li-Ion: 4.40V |
| < 3.0kΩ | No charge (short-circuit) |
If either a short- or open-circuit condition is detected, charger stops operation and remains in the FAULT state until the input or TS pin is toggled.
Once a valid resistor value has been detected, the corresponding charge voltage is latched in and the pin is not continuously monitored during operation. A change in this pin will not be acknowledged by the IC until the input supply or TS pin is toggled.
