MC33931 Simplified Application Drawing


Key Features

  • 8.0 V to 28 V continuous operation (transient operation from 5.0 V to 40 V)
  • 235mΩ maximum RDS(ON) @ Tj=150°C (each H-Bridge MOSFET)
  • 3.0 V and 5.0 V TTL / CMOS logic compatible inputs
  • Over-current limiting (regulation) via internal constant-off-time PWM
  • Output short-circuit protection (short to VPWR or GND)
  • Temperature-dependant current-limit threshold reduction
  • All inputs have an internal source/sink to define the default (floating input) states
  • Sleep mode with current draw < 50μ A (each half with inputs floating or set to match default logic states)
