Product Overview

MC33772BSP1AE 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.
  • 5V ≤ VPWR ≤ 30V operation, 40V transient
  • 3 to 6 cells management, 0.8mV total cell voltage measurement error
  • Isolated 2Mbps differential communication or 4.0 Mbps SPI
  • Addressable on initialization, qualified in compliance with AEC-Q100
  • Synchronized cell voltage/current measurement with coulomb count
  • Total stack voltage measurement, seven GPIO/temperature sensor inputs
  • 5V reference supply output with 5mA capability
  • Automatic over/undervoltage and temperature detection routable to fault pin
  • Integrated sleep mode over/undervoltage and temperature monitoring
  • 48 pin LQFP package, operating temperature range from -40°C to 125°C
