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 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 control cell charge,
discharge, and cell voltage balancing.
Over-charge,
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.
over-discharge,
and
over-current
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 “l(fā)ock in”
written battery cell/pack data.
The X3100 and X3101 are each housed in a 28 Pin
TSSOP package.
