Qorvo PAC22140 Smart BMS with 32kB Flash & 8kB SRAM

　　Qorvo PAC22140 Smart Battery Monitoring System (BMS) with 32kB Flash and 8kB SRAM monitors 10-series to 20-series Li-ion, Li-polymer, and LiFePO4 battery packs. The PAC22140 integrates a fully programmable 50MHz 32-bit Arm Cortex M0 microcontroller and includes cell balancing, monitoring, and protection for the battery packs. 

      The module provides access to multiple analog and digital peripherals required to manage high-cell-count battery packs. These include a programmable-gain differential amplifier, a 10-bit SAR ADC, and multiple 16-bit Sigma-Delta ADCs for current and voltage sensing. A single-supply 145V buck DC/DC controller generates a 5V system rail to power the PAC22140, and an integrated charge pump supports the charge and discharge FET drivers.

　　Qorvo PAC22140 Smart BMS comes in a 9mm x 9mm, 60-pin QFN package for compact battery-monitoring applications, such as E-transportation, garden tools, power tools, and broad industrial battery management. Supported serial interfaces include UART/SPI and I2C/SMBus.
