SW7 controls the maximum charge current limit.
| Switch | Function | Parameter controlled |
|---|---|---|
| SW7 | Charge current limit | ICHG |
SW7 is a 5-pole dip switch that can select the five defined current limits in the following table. This is done by setting the resistance from ICHG to GND. Closing multiple switches simultaneously decreases the resistance and increases the current limit. The user configured current limit can be set by leaving all switches open and selecting an appropriate R12 value.
| ICHG | Charge current | R_ICHG |
|---|---|---|
| 1 | 400 mA | 0 Ω |
| 2 | 250 mA | 1.0 kΩ |
| 3 | 150 mA | 2.7 kΩ |
| 4 | 50 mA | 12 kΩ |
| 5 | 20 mA | 27 kΩ |
