Introduction

AI Translation

33771 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 such as energy storage systems (ESS) and uninterruptible power supply (UPS) systems. The device performs ADC conversion on differential battery cell voltage and current, and conducts battery coulomb counting and battery temperature measurement. This information is digitally transmitted to the microcontroller via Serial Peripheral Interface (SPI) or Transformer Isolation (TPL) for processing.

Features

AI Translation
  • Operating voltage 9.6 V ≤ V_PWR ≤ 61.6 V, transient voltage 75 V
  • 7 to 14 cell management
  • Isolated 2.0 Mbps differential communication or 4.0 Mbps SPI
  • Addressable during initialization
  • 0.8 mV maximum total voltage measurement error
  • Synchronized cell voltage/current measurement and coulomb counting
  • Battery pack total voltage measurement
  • 7 GPIO/temperature sensor inputs
  • 5.0 V reference power output, 5.0 mA current capability
  • Automatic overvoltage/undervoltage and temperature detection, routable to fault pin
  • Integrated sleep mode overvoltage/undervoltage and temperature monitoring
  • On-board 300 mA passive cell balancing with diagnostics
  • Hot-swap internal and external fault detection (e.g., open circuit, short circuit, and leakage)
  • ISO 26262 support up to ASIL D safety systems
  • Fully compatible with MC33772 supporting up to 6 cells; AEC-Q100 compliant

Applications
