    The Qorvo® PAC22140 is a Smart Battery Monitoring System (BMS) that can monitor 10-series to 20-series Li-Ion, Li-Polymer and LiFePO4 battery packs. The PAC22140 integrates a FLASH-programmable MCU, Power Management, Current/Voltage/Temperature Sense and drive circuits for charge/discharge FETs and protection fuses. It can communicate using UART/SPI or I2C/SMBus serial interfaces.

    The PAC22140 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. There are high-side gate drivers for a charge and discharge FET, as well as a low-side driver to blow a battery pack fuse. The device also integrates a programmable-gain differential amplifier and 16-bit Sigma-Delta ADC for current sense as well as a 16-bit Sigma-Delta ADC for cell balancing voltage sense and a 10-bit SAR ADC for additional voltage and temperature sense usage.

    The PAC22140 is packaged in an 9 x 9 mm, 60-pin QFN package for compact, high cell count battery-monitoring applications.

    PAC22140EVK1 Evaluation Kit

    PAC22140EVK1

    Qorvo's PAC22140EVK1 development platform is a complete hardware solution enabling users not only to evaluate the PAC22140 device, but also develop Smart Battery Management System (BMS) solutions by taking advantage of the fully integrated Arm® Cortex®-M0 based microcontroller with BMS specific Analog Front End. The module contains a PAC22140 Power Application Controller® (MCU) and all the necessary circuitry to properly energize the MCU and its internal peripherals once power is applied.

    To aid in the application development the PAC22140EVK1 offers access to each and every one of the PAC22140 device's signals by means of a series of male header connectors.

    Supporting Evaluation Tools

    ET-UARTSWD

    The ET-UARTSWD adapter is the preferred adapter for evaluation of PAC devices/firmware and combines a USB to UART adapter with SWD debugger connector adaptation into a single board with isolation. The ET-UARTISO-1 adapter provides only the USB to UART adapter with isolation for Qorvo application GUI communications.

    ET-UARTSWD

    The ET-UARTSWD isolated communications and debugging interface unifies two modules into one. Previously, interfacing a PC Computer to any of Qorvo's PAC5xxx Evaluation Modules required one module to enable UART based serial communications and a second module to allow for in-system debugging and FLASH memory programing.
