MC33926 - 5.0A throttle control H-bridge

General Description

The 33926 is a SMARTMOS monolithic H-bridge power IC 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.

Key Features

  • 5.0 V to 28 V continuous operation (transient operation from 5.0 V to 40 V) NXP Semiconductors MC33926 5.0 A throttle control H-bridge.
  • 225 mΩ maximum RDS(on) at 150 °C (each H-bridge MOSFET).
  • 3.0 V and 5.0 V TTL/CMOS logic compatible inputs.
  • Overcurrent limiting (regulation) via an internal constant-off-time PWM.
  • Output short-circuit protection (short to VPWR or ground).
  • Temperature dependent current limit threshold reduction.

MC33926 5.0 A throttle control H-bridge Rev. 16 — 19 February 2020 Data sheet: technical data 1 General description The 33926 is a SMARTMOS monolithic H-bridge power IC 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. It meets the stringent requirements of automotive applications and is fully AEC-Q100 grade 1 qualified. The 33926 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.
