Battery Management

BMS stands for Battery Management System. It is a device that monitors and manages the status of battery cells, usually represented as a circuit board or a hardware box in BMS.

The FT92051B/92071B/92101B launched provide comprehensive protection and balanced management for 3-5/3-7/3-10 series connected lithium battery packs (cells). The chip samples voltage, current, and temperature, and provides flexible protection through upper computer configuration, eliminating the limitations of a single part number. The internal balanced current of the chip is 10mA, and it can be externally expanded for high current balancing. Chip load detection and charger detection do not require the addition of peripheral devices. External control lock mode reduces power consumption to 2 µ A, reduces battery cell loss during transportation or storage, and also turns off charging and discharging functions to improve safety. The high-voltage pin can withstand up to 74V, providing sufficient voltage margin.
