QORVO PAC22140 smart battery monitoring system (BMS) can monitor 10-series to 20-series Li-Ion, Li-Polymer and LiFePO4 battery packs. Device integrates a FLASH-programmable MCU, power management, current/voltage/temperature sense and drive circuits for charge/discharge FETs and protection fuses. Device can communicate using UART/SPI or I2C/SMBus serial interfaces. Device contains an Arm Cortex-M0 with 32kB of FLASH and 8KB of SRAM and has access to several different analog and digital peripherals that is intended to be used for the fuel gauging algorithm and system telemetry reporting. There is a single supply 145V input Buck dc-dc controller, used to generate gate drive voltages for external charge and discharge FETs and external FUSE FET, as well as all the sub-regulators required for the MCU and other sub-systems in the device.
