Introduction

AI Translation

The 33772 is a SMARTMOS lithium-ion battery cell controller IC designed for automotive applications such as hybrid electric vehicles (HEV) and electric vehicles (EV), as well as industrial applications including energy storage systems (ESS) and uninterruptible power supply (UPS) systems. The device performs ADC conversion on differential battery cell voltages and currents, and conducts battery coulomb counting and battery temperature measurement. This information is digitally transmitted to a microcontroller for processing via SPI or transformer-isolated link (TPL).
