Pin Functions
| PIN | I/O | DESCRIPTION | |
|---|---|---|---|
| NAME | NUMBER | ||
| CHG | C1(1) | Low (FET on) indicates charging and open drain (FET off) indicates no charging or the first charge cycle complete. | |
| IN | A2 | I | Input power, connected to external DC supply (AC adapter or USB port). Expected range of bypass capacitors 1 μF to 10 μF, connect from IN to VSS. |
| ISET | B2 | I | Programs the fast-charge current setting. External resistor from ISET to VSS defines fast charge current value. Recommended range is 13.5 kΩ (10 mA) to 0.54 kΩ (250 mA). |
| OUT | A1 | O | Battery Connection. System Load may be connected. Expected range of bypass capacitors 1 μF to 10 μF. |
| PRE-TERM | C1(1) | I | Programs the current termination threshold ( 1% to 50% of Iout, 1mA minimum). The pre-charge current is twice the termination current level. |
| Expected range of programming resistor is 600 Ω to 30 kΩ (6k: Ichg/10 for term; Ichg/5 for precharge) | |||
| TS | B1 | I | Temperature sense pin connected to 10k at 25°C NTC thermistor, in the battery pack. Floating TS pin or pulling high puts part in TTDM “Charger” mode and disables TS monitoring, Timers and Termination. Pulling pin low disables the IC. If NTC sensing is not needed, connect this pin to VSS through an external 10-kΩ resistor. A 250-kΩ resistor from TS to ground will prevent IC entering TTDM mode when battery with thermistor is removed. |
| VSS | C2 | – | Ground pin |
