JW3370 4~10 Series Cell Battery Monitor and Protection IC FEATURES 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. ⚫ ⚫ ⚫ pe lU JW3370 integrates complete protection function including over/under voltage, over/under temperature, over charge/discharge current, short-circuit and open wire detection. When fault(s) happen, JW3370 will send alarm signal to inform host and shutdown CHG or DSG. JW3370 integrated pre-charge and pre-discharge drivers for the deep discharge battery or some big capacitor load startup. JW3370 supports both Sleep mode and Ship mode to achieve high efficiency with low power when charge/discharge current is minor. O ⚫ JW3370 communicates with external control unit via SPI interface. More JW3370 can operate in series to monitor long string battery.
