BQ27541DRZT-V200 Datasheet PDF - TI

●The BQ27541DRZT-V200 is a Li-ion Battery Fuel Gauge provides fuel gauging for single-cell Li-ion battery packs. The device requires little system microcontroller firmware development for accurate battery fuel gauging. The BQ27541 resides within the battery pack or on the system"s main-board with an embedded battery (nonremovable). It 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) and temperature (°C). It features integrated support for secure battery pack authentication, using the SHA-1/HMAC authentication algorithm.

● Microcontroller peripheral

● Accurate battery fuel gauging

● Internal temperature sensor for system temperature reporting

● SHA-1/HMAC Authentication

● Lifetime data logging

● Automatically adjusts for battery aging, battery self-discharge and temperature/rate inefficiencies

● 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.
