The SA63654 device is a highly integrated, high-accuracy and higher ASIL-level battery monitor and protector for 4-series Li-Ion, Li-Polymer, and LiFePO4 battery packs. The device consists of battery monitor (cell voltage, pack current, temperature, pack coulomb counter), cell balance, pack high-side NMOS FET driver and secondary protection, which can cover the dection of Over-Voltage(OV), Under-Voltage(UV), Over-Current (OC), Over-Temperature(OT), Under-Temperature(UT), Load Change and Low SOC. The device integrates low-side current measurement and overcurrent detection.
The device supports 6MHz SPI communication with MCU. There are 3 operation modes: SHUTDOWN mode,SLEEP mode(cyclic wakeup),ACTIVE mode. When not activated, the device offers an extremely low power consumption in SLEEP mode. The device is available in a 40-pin Wettable Flank QFN package.
