PAC25140N数据手册Qorvo中文资料规格书

描述 Description

The Qorvo® PAC25140N is a Intelligent Battery Monitoring System (BMS) that can monitor 10-series to 20-series Li-Ion, Li-Polymer and LiFePO4 battery packs. The PAC25140N 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 CAN/UART/SPI or I2C/SMBus serial interfaces. The PAC25140N contains an Arm® Cortex®-M0 with 128kB of FLASH and 32KB 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 12-bit SAR ADC for additional voltage and temperature sense usage. The PAC25140N is packaged in an 10x10mm with offset exposed pad, 68-pin TSLP package for compact, high cell count battery-monitoring applications.
