PRELIMINARY

DESCRIPTION

3 or 4 Cell Li-Ion Battery Protection and

Monitor IC

The X3100 is a protection and monitor IC for use in bat-

tery packs consisting of 4 series Lithium-Ion battery

cells. The X3101 is designed to work in 3 cell applica-

tions. Both devices provide internal over-charge, over-

discharge, and over-current protection circuitry, internal

EEPROM memory, an internal voltage regulator, and

internal drive circuitry for external FET devices that con-

trol cell charge, discharge, and cell voltage balancing.

FEATURE

• Software Selectable Protection Levels and

Variable Protect Detection/Release Times

• Integrated FET Drive Circuitry

• Cell Voltage and Current Monitoring

• 0.5% Accurate Voltage Regulator

• Integrated 4kbit EEPROM

• Flexible Power Management with 1µA Sleep

Mode

• Cell Balancing Control

Over-charge, over-discharge, and over-current thresh-

olds 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.

BENEFIT

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 con-

verter. Software on this microcontroller implements

gas gauge and cell balancing functionality in software.

• Optimize protection for chosen cells to allow

maximum use of pack capacity.

• Reduce component count and cost

• Simplify implementation of gas gauge

• Accurate voltage and current measurements

• Record battery history to optimize gas gauge,

track pack failures and monitor system use

• Reduce power to extend battery life

• Increase battery capacity and improve cycle life

battery life

The X3100 and X3101 contain a current sense ampli-

fier. Selectable gains of 10, 25, 80 and 160 allow an

external 10 bit A/D converter to achieve better resolu-

tion 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.
