Overview
A single-cell gauge that requires minimal user configuration and system microcontroller firmware development, leading to quick system bring-up. The bq27220 device uses the Compensated End-of-Discharge Voltage (CEDV) algorithm for fuel gauging, and provides information such as remaining battery capacity (mAh), state-of-charge (%), runtime-to-empty (min), battery voltage (mV), temperature (°C), and state-of-health (%). The bq27220 battery fuel gauge has ultra-low power consumption in NORMAL (50 μA) and SLEEP (9 μA) modes, leading to longer battery runtime. Configurable interrupts help save system power and free up the host from continuous polling. Accurate temperature sensing is supported via an external thermistor. Customers can use preloaded CEDV parameters in ROM or can generate custom chemistry parameters using TI's web-based tool, GAUGEPARCAL. Custom-generated parameters can be either programmed in the device RAM by the host on power up of the system or customers can program the parameters to an onboard One-Time Programmable (OTP) memory. Battery fuel gauging with the bq27220 device requires connections only to PACK+ (P+) and PACK– (P-) for a removable battery pack or embedded battery circuit. The tiny, 9-ball, 1.62 mm×1.58 mm, 0.5 mm pitch NanoFree chip scale package (DSBGA) is ideal for space-constrained applications.
