MC33771BSA2AE [NXP]

The MC33771B is a battery cell controller IC that performs ADC conversions of differential cell voltages and current, battery coulomb counting, and temperature measurements. It supports 7 to 14 cells management with 9.6 V ≤ V ≤ 61.6 V operation and 75 V transient. The device features isolated 2.0 Mbps differential communication or 4.0 Mbps SPI, 0.8 mV maximum total voltage measurement error, synchronized cell voltage/current measurement with coulomb count, seven GPIO/temperature sensor inputs, 5.0 V at 5.0 mA reference supply output, automatic over/undervoltage and temperature detection, onboard 300 mA passive cell balancing with diagnostics, hot plug capability, and detection of internal and external faults. It is designed to support ISO 26262 up to ASIL D safety capability and is qualified in compliance with AECQ-100.
