Input power, connected to external DC supply (AC adapter or USB port). Expected range of bypass IN A2 I capacitors 1 μF to 10 μF, connect from IN to VSS. Programs the fast-charge current setting. External resistor from ISET to VSS defines fast charge ISET B2 I current value. Recommended range is 13.5 k Ω (10 mA) to 0.54 kΩ (250 mA). Battery Connection. System Load may be connected. Expected range of bypass capacitors 1 μF to OUT A1 O 10 μF. Programs the current termination threshold ( 1% to 50% of Iout, 1mA minimum). The pre-charge PRE-TERM C1(1) I 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) 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 TS B1 I Termination. Pulling pin low disables the IC. If NTC sensing is not needed, connect this pin to VSS through an external 10-k Ω resistor. A 250-kΩ resistor from TS to ground will prevent IC entering TTDM mode when battery with thermistor is removed.
