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.
