The BQ27532YZFT-G1 is a system-side Li-ion Battery Management Unit provides Impedance Track™ fuel gauging and charging control for single-cell Li-ion battery packs. The fuel gauge requires little system microcontroller firmware development. Together with BQ2425X single-cell switch-mode charger, the fuel gauge manages an embedded battery (non-removable) or a removable battery pack. The fuel gauge uses the patented Impedance Track algorithm for fuel gauging and provides information, such as remaining battery capacity (mAh), state-of-charge (%), runtime-to-empty (minimum), battery voltage (mV), temperature (°C) and SoH (%). Battery fuel gauging with the device requires only PACK+ (P+), PACK- (P-) and thermistor (T) connections to a removable battery pack or embedded battery circuit.
● Resides on system main board
● Charger control based on SoH
● Temperature level charging (TLC)
● Configurable charge voltage and current based on temperature
● Improved recharged thresholds
● Tighter accuracy controls for charger termination
● Higher safety and security
● Green product and no Sb/Br
●Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
