Product Overview

The BQ27621YZFT-G1A is a system-side Fuel Gauge with dynamic voltage correlation. It is a minimally configured microcontroller peripheral that provides system-side fuel gauging for single-cell Li-ion batteries. The device requires very little user configuration and system microcontroller firmware development. The bq27621-G1 uses the dynamic voltage correlation algorithm for fuel gauging. This process eliminates the need for a sense resistor when calculating remaining battery capacity (mAh), state-of-charge (%), battery voltage (mV) and temperature (°C). Battery fuel gauging with the BQ27621-G1 requires connections only to PACK+ (P+) and PACK- (P-) for a removable battery pack or embedded battery circuit.
  • Resides on system board
  • Supports embedded or removable batteries
  • Powered directly from battery with integrated LDO
  • Easy to configure fuel gauging based on the dynamic voltage correlation algorithm
  • Reports remaining capacity and state of charge (SOC) with smoothing filter
  • Automatically adjusts for self-discharge, temperature and rate changes
  • Configurable SOC interrupt or battery low digital output warning
  • Green product and no Sb/Br
