JW3370 Overview
Description
JW3370 is a multi-cell battery stack monitoring and protection IC that includes a 14-bit ADC for battery voltage and temperature sense, a 16-bit ADC for charge/discharge current sense. JW3370 provides passive balance function for each cell and allows at most 3 consecutive cells being discharged simultaneously.
