MC33772BTC0AER2

MC33772BTC0AER2 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 Serial Peripheral Interface (SPI) or Transformer Isolation (TPL) to a microcontroller for processing. Designed to support ISO 26262 up to ASIL D safety system. It is fully compatible with the MC33771 for a maximum of 14 cells.
