Gas Gauge IC with External Charge Control
Features General Description вћ¤ Conservative and repeatable
measurement of available charge
in rechargeable batteries The bq2014 Gas Gauge IC is intended for battery-pack or in-system
installation to maintain an accurate
record of available battery charge.
The IC monitors the voltage drop
across a sense resistor connected in
series between the negative battery
terminal and ground to determine
charge and discharge activity of the
battery. вћ¤ Charge control output operates an
external charge controller such as
the bq2004 Fast Charge IC
вћ¤ Designed for battery pack integration -120ВµA typical standby current вћ¤ Display capacity via single-wire
serial communication port or direct drive of LEDs
вћ¤ Measurements compensated for
current and temperature
вћ¤ Self-discharge compensation using
internal temperature sensor
вћ¤ User-selectable end-of-discharge
threshold …
