BQ27505-J3中文资料系统侧 Impedance Track™ 电量监测计，固件版本为 v2.20数据手册TI规格书

描述 Description

The Texas Instruments bq27505 system-side Li-Ion battery fuel gauge is a microcontroller peripheral that provides fuel gauging for single-cell Li-Ion battery packs. The device requires little system micro- controller firmware development. The bq27505 resides on the system’s main board and manages an embedded battery (non-removable) or a removable battery pack. The bq27505 uses the patented Impedance Track™ algorithm for fuel gauging, and provides information such as remaining battery capacity (mAh), state-of- charge (%), run-time to empty (min), battery voltage (mV), temperature (°C) and state of health (%).Battery fuel gauging with the bq27505 requires only PACK+ (P+), PACK– (P–), and Thermistor (T) connections to a removable battery pack or embedded battery circuit. The CSP option is a 12-ball package in the dimensions of 2,43 mm × 1,96 mm with 0,5 mm lead pitch. It is ideal for space constrained applications.
