BATTERY PROTECTION IC FOR 2-SERIAL-CELL PACK

(1) Internal high-accuracy voltage detection circuit

(2) High input-voltage device : Absolute maximum ratings 18 V.

(3) Wide operating voltage range : 2 to 16 V

(4) The delay time for every detection can be set via an external capacitor.

(5) Two overcurrent detection levels (Protection for short-circuiting)

(6) Internal auxiliary over voltage detection circuit (Fail-safe for overcharge detection voltage)

(7) Internal charge circuit for 0 V battery (Unavailable is option)

(8) Low current consumption

(9) Lead-free products

• Lithium-ion rechargeable battery packs

• Lithium- polymer rechargeable battery packs

Features

• Overcharge detection voltage

• Overcharge release voltage

• Overdischarge detection voltage 1.70 V ± 80 mV to 2.60 V ± 80 mV

• Overdischarge release voltage

• Overcurrent detection voltage 1

• Operation mode

• Power-down mode 0.2 nA typ. 0.1 µA max. (− 40 to + 85 °C)
