SLUSCG9A – FEBRUARY 2016 – REVISED MARCH 2016 bq27320 Single-Cell CEDV Fuel Gauge
1 Features 3 The Texas Instruments single-cell bq27320 battery
fuel gauge requires very minimal configuration and
system microcontroller firmware development, leading
to quick system bring-up. The bq27320 uses the
Compensated End-of-Discharge Voltage (CEDV) gas
gauging algorithm for fuel gauging, and provides
information such as remaining battery capacity
(mAh), state-of-charge (%), runtime-to-empty (min),
battery voltage (mV), temperature (В°C) and state-ofhealth (%). 1 Battery Fuel Gauge For System-/Pack-Side
Configuration
Compensated End-of-Discharge Voltage (CEDV)
Gauging Technology
– Adjusts for Battery Aging, Self-Discharge,
Temperature, and Rate Changes
– Reports Remaining Capacity, State-of-Charge
(SOC), and Time-to-Empty with Smoothing …
