MC33771BSB1AE
Description
The 33771 is a SMARTMOS lithium-ion battery cell controller IC designed for automotive applications, such as hybrid electric (HEV) and electric vehicles (EV) along with industrial applications, such as energy storage systems (ESS) and uninterruptible power supply (UPS) systems. The device performs ADC conversions of the differential cell voltages and current, as well as battery coulomb counting and battery temperature measurements.

- Isolated 2.0 Mbps differential communication or 4.0 Mbps SPI
- Addressable on initialization
- 0.8 mV maximum total voltage measurement error
- Synchronized cell voltage/current measurement with coulomb count
- Total stack voltage measurement
- Seven GPIO/temperature sensor inputs
- 5.0 V at 5.0 mA reference supply output
- Automatic over/undervoltage and temperature detection routable to fault pin
