Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is
a stress rating only; the functional operation of the device (at these or any other conditions above those indicated in
the operational sections of this specification) is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.




Description

The X3100 is a protection and monitor IC for use in battery packs consisting of 4 series Lithium-Ion battery cells. The X3101 is designed to work in 3 cell applications. Both devices provide internal overcharge,over-discharge, and over-current 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.

X3100, Over-charge, over-discharge, and over-current thresholds reside in an internal EEPROM memory register and are selected independently via software using a 3MHz SPI serial interface. Detection and timeout delays can also be individually varied using external capacitors.

Using an internal analog multiplexer, the X3100 or X3101 allow 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 X3100 and X3101 contain 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 X3100 and X3101 are each housed in a 28 Pin TSSOP package.
