JW3371 4~10 Series Cell Battery Monitor and Protection IC DESCRIPTION FEATURES JW3371 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.    JW3371 provides passive balance function for each cell and allows at most 3 consecutive cells being discharged simultaneously. JW3371 communicates with external control unit via SPI interface. More JW3371 can operate in series to monitor long string battery. JW3371 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, JW3371 will send alarm signal to inform host and shutdown CHG or DSG. m JW3371 integrated pre-charge and pre-discharge drivers for the deep discharge battery or some big capacitor load startup.          JW3371 supports both Sleep mode and Ship mode to achieve high efficiency with low power when charge/discharge current is minor. rC    Company’s Logo is Protected, “JW” and “JOULWATT” are Registered Trademarks of Joulwatt Technology Co., Ltd.  Monitor 10 Series Cell Battery and Support Series Operation 14-bit ΔΣ ADC Samples Battery Voltage and Accuracy is ±3mV typ.@ (2.3~4.3V, TA=25ºC) Provide Filtering 3 Channels Thermal Sense and Accuracy is ±1℃(No Considering NTC Resistor Offset) Battery Over/Under Voltage Protection Battery Over/Under Temperature Protection Open Wire Connection Detection 10 Cells Passive Balance On-Chip Passive Cell Balancing Switches Provide Off-Chip Passive Balancing 16-bit ΔΣ ADC Senses Charge/Discharge Current and Accuracy is ±75µV typ.@ (-100 mV ~100mV, TA=25ºC) ±100µV typ.@ (-190 mV ~190mV, TA=25ºC) Over Charge/Discharge Current Protection Discharge Short Protection Reliable SPI Communication (Mode3) 3.3V LDO Output for External Application External Protection N-MOSFETs Integrated Pre-charge/discharge Function Low Power Consumption During Operation 1.5mA typ. 1.8mA Max During Sleep 18µA typ. 20µA Max During Ship 3.2µA typ. 5µA Max Package: TSSOP38 APPLICATIONS    Electric Bicycles, Motorcycles.
