JW3376 11~16 Series Cell Battery Monitor and Protection IC DESCRIPTION FEATURES JW3376 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. JW3376 provides passive balance function for each cell and allows at most 3 consecutive cells being discharged simultaneously. JW3376 communicates with external control unit through SPI interface, and the interface is configured to operate in a system using CPHA=1 and CPOL=1.         p JW3376 integrates complete protection function including over/under voltage, over/under temperature, charge/discharge over current, load short-circuit and battery open-wire detection. When fault(s) happen, JW3376 will send alarm signal to inform host and shutdown CHG or DSCHG  o JW3376 integrated pre-charge and predischarge drivers for the deep discharge battery or some big capacitor load startup. r JW3376 supports both Sleep mode and Ship mode to achieve high efficiency with low power when the charge/discharge current is small.
