XM3100 Datasheet | Xicor

FEATURE - plete Solution for 3-4 Cell Li-Ion battery pack - X3100 and microcontroller control .. BENEFIT - Minimal design effort required - Safe, accurate and flexible implementation. - No algorithms to develop - Custom software modules add more gas gauge capability, cell balancing, history tracking. - Conforms to industry smart battery standards gas gauging function. Future versions of the board will offer more extensive gas gauging, cell balancing routines and pack history tracking. The XM3100 board has outputs for a separate display board containing five LEDs and a puchbutton switch. This board is included with the XM3100. The LEDs and switch allow the battery pack user to check the state of charge without connecting the battery to the host. The LEDs turn on for a short period of time when the switch is pressed to show capacity as 10%, 30%, 50%, 70% or 90% of full charge. The XM3100 board can be tailored to meet specific customer requirements. The module over-voltage, overcurrent, and under-voltage levels are easily changed through programmable non-volatile bits. Simple capacitor changes provide different protection time-out periods. Specialized software routines can offer customized gas gauging. - Built-in Gas Gauge Software - General Purpose Microcontroller - SMBus interface/SBS 1.1 pliant DESCRIPTION The XM3100 module is a plete battery pack solution that features the Xicor X3100 Lithium Ion battery protection and monitor IC. For use in battery packs consisting of 3 or 4 Lithium-Ion battery cells (10.8V or 14.4V packs) the X3100 provides over-voltage, undervoltage, and over-current protection circuitry, internal EEPROM memory, an internal voltage regulator, and drive circuitry for switching external FET devices used to control cell charge, discharge, and cell voltage balancing. The XM3100 module provides all external devices needed to control the battery pack including a preprogrammed microcontroller. This microcontroller has a System Management Bus (SMBus...
