1 Product Summary

The 33772B 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. The information is digitally transmitted through the SPI or transformer

isolation to a microcontroller for processing.
