Description:

The MC33771BSP1AE is a lithium-ion battery controller IC for automotive and industrial control applications such as HEV, EV, ESS, and UPS systems.The device provides ADC conversion of differential battery voltage and current, as well as battery coulomb counting and battery temperature measurement. The information is digitally transferred to the microcontroller for processing via a serial peripheral interface (SPI) or transformer-isolated (TPL).

Features:

- 9.6 V ≤ VPWR ≤ 61.6 V operating voltage, 75 V transient voltage

- 7 to 14 cell management

- Isolated 2.0 Mbps differential communication or 4.0 Mbps SPI

- Addressable at initialization

- 0.8 mV maximum total voltage measurement error

- Synchronized cell voltage/current measurement with coulomb counting

- Total stack voltage measurement

- Seven GPIO/temperature sensor inputs

- 5.0 V reference supply output at 5.0 mA

- Automatic overvoltage/undervoltage and temperature detection with routing to fault pins

- Integrated sleep mode over/under voltage and temperature monitoring

- On-board 300 mA passive battery balance with diagnostics

- Hot-swap capability

- Detects internal and external faults such as opens, shorts and leaks

- Designed to support ISO 26262 and ASIL D safety systems

- Fully compatible with MC33772, supports up to six cells

- AEC-Q100 compliant
