1 pcs : BQ79631PAPRQ1 - Battery Management Automotive high-voltage battery pack monitor with voltage, current and insulation res

bq79631-Q1 Battery Monitor & Balancer Texas Instruments bq79631-Q1 Battery Monitor and Balancer provides high-accuracy measurement capable of measuring divided down voltages from high voltage nodes. These voltage nodes include Pack+ (HV Battery Positive terminal), Fuse, Charge (Port), Link (Load) in a battery junction box (BJB), or battery disconnect unit (BDU) system. Key voltage measurements can make use of the integrated digital low-pass filters. The device has a highly accurate integrated current sense ADC capable of measuring current in a low-side shunt resistor. The device can measure the insulation resistance with internal ADC and control any switching scheme needed for this measurement. Eight GPIOs/auxiliary inputs can be used for thermistor measurement, driving relays, measuring voltages, and being a master SPI interface to peripheral SPI devices. The isolated bi-directional daisy-chain ports support both capacitor or transformer-based isolation. The device also supports communication over UART.
