3 Cell Li-Ion Battery Protection and

Monitor IC

The X3102 is a protection and monitor IC for use in battery

packs consisting of 3 series Lithium-Ion battery cells. The

device provides internal over-charge, over-discharge, and

overcurrent protection circuitry, internal EEPROM memory,

an internal voltage regulator, and internal drive circuitry for

external FET devices that control cell charge, discharge, and

cell voltage balancing.

Over-charge, over-discharge, and overcurrent thresholds

reside in an internal EEPROM memory register and are

selected independently via software using a 3MHz SPI serial

interface. Detection and time-out delays can also be

individually varied using external capacitors.

Using an internal analog multiplexer, the X3102 allows

battery parameters such as cell voltage and current (using a

sense resistor) to be monitored externally by a separate

microcontroller with A/D converter. Software on this

microcontroller implements gas gauge and cell balancing

functionality in software.

The X3102 contains a current sense amplifier. Selectable

gains of 10, 25, 80 and 160 allow an external 10 bit A/D

converter to achieve better resolution than a more expensive

14 bit converter.

An internal 4kbit EEPROM memory featuring IDLock™,

allows the designer to partition and “lock in” written battery

cell/pack data.

The X3102 is housed in a 28 Pin TSSOP package.
