Function

1

TIN Temperature sensing input(also battery connecting detection input)

2

C3 Delay time setting for temperature sensing (Tpd = 49ms @ 0.1uF)

Setting 4.1V type battery or 4.2V type battery

3 VrefSW •For 4.1V type battery, VrefSW pin and VDD pin are shorted.

•For 4.2V type battery, VrefSW pin is opened.

Reference voltage output
