DESCRIPTION
Low (FET on) indicates charging and open drain (FET off) indicates no charging or the first charge
cycle complete.
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 V_SS.
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).
O
Battery Connection. System Load may be connected. Expected range of bypass capacitors 1 μF to
10 μF.
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)
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
I 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.
