JW3312 - Battery Protection

General Description

JW®3312 is a battery protection IC for the 3~5 cells rechargeable lithium-ion battery pack.

JW3312 integrates high-accuracy voltage detection circuits, which realizes multiple protection functions including over-charge, over-discharge, over-current, over-temperature and VC5~VC0 pins open-wire.

Key Features

  • Wide range of operation voltage 5V to 35V.
  • Monitor 3~5 series battery pack.
  • High-accuracy voltage detection for each cell - Over-charge detection voltage VOC: 3.6~4.5V (50mV step) ±25mV - Over-charge release hysteresis VOCRH: 0V/0.1V/0.2V/0.35V - Over-discharge detection voltage VOD: 2.1~3.1V (100mV step) ±50mV - Over-discharge release hysteresis VODRH: 0V/0.1~0.6V (100mV step).
  • Discharge over-current detection in 3-step - 1st detection voltage VDOI1: 0.050~0.25V (50mV step).
