The BQ77PL900 from Texas Instruments is an integrated circuit designed for primary protection of 5 to 10 series cell lithium-ion and lithium-polymer battery packs. It functions as both a battery protector and an analog front end (AFE), offering comprehensive safety features.
Key electrical specifications include a wide supply voltage range from 7 V to 50 V and a low typical supply current of 450 μA. The device integrates two LDOs: a 5-V, 25-mA LDO and a 3.3-V, 25-mA LDO, which can be used to power a host controller or support circuitry. It is capable of operating with a low 1-mΩ sense resistor for current monitoring.
The BQ77PL900 provides programmable thresholds and delay times for overvoltage, undervoltage, overcurrent in discharge, and short circuit in discharge conditions. It also features fixed overtemperature protection. Communication and control can be managed via an I2C interface for host control mode, or it can operate in a stand-alone mode for pack protection control and recovery.
This IC is suitable for applications such as cordless power tools, power-assisted bicycles/scooters, uninterruptible power supply (UPS) systems, and medical equipment. It is available in an SSOP (DL) package with dimensions of 15.88 mm x 10.35 mm.
