Xicor X3101
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. The X3100 and X3101 are each housed in a 28 Pin TSSOP package.| Part No. | X3101 |

DESCRIPTION
The X3100 is a protection and monitor IC for use in battery packs consisting of 4 series Lithium-Ion battery cells. 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.
