DESCRIPTION
JW?3370 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.
JW3370 communicates with external control unit
via SPI interface. More JW3370 can operate in
series to monitor long string battery.
JW3370 integrates complete protection function
including over/under voltage, over/under
temperature, over charge/discharge current, short
and open wire.
JW3370 supports both Sleep mode and Ship
mode to achieve high efficiency with low power
when charge/discharge current is minor.
