3 Or 4 Cell Li-Ion Battery Protection And Monitor IC

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 over-charge, overdischarge, 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.
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 time-out 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.
