Roll over image to zoom in

The NXP MC33931 is a monolithic H-Bridge power IC in a robust thermally enhanced package, designed primarily for automotive electronic throttle control, but is applicable to any low-voltage DC servo motor control application within the current and voltage limits stated in this specification.

  • The MC33931 H-bridge is able to control inductive loads with currents up to 5.0 A peak
  • RMS current capability is subject to the degree of heatsinking provided to the device package. Internal peak-current limiting (regulation) is activated at load currents above 6.5 A ±1.5 A
  • Output loads can be pulse-width modulated at frequencies up to 11 kHz
  • Processor Expert® component for medium voltage H-Bridge products enables rapid embedded application development.

Features

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)
