MC33926PNB Product Details

The 33926 is a 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.

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. Output loads can be pulse width modulated (PWM-ed) at frequencies up to 20 kHz. A load current feedback feature provides a proportional (0.24% of the load current) current output suitable for monitoring by a microcontroller's A/D input. A Status Flag output reports undervoltage, overcurrent, and overtemperature fault conditions.

Two independent inputs provide polarity control of two half-bridge totem-pole outputs. Two independent disable inputs are provided to force the H-Bridge outputs to tri-state (high impedance off-state). An inverting input changes the IN1 and IN2 inputs to LOW = true logic.

The MC33926PNB is a SafeAssure® functional safety solution



  • 8.0 V to 28 V Continuous Operation (Transient Operation from 5.0 V to 40 V)
  • 225 mOhm maximum RDS(ON) @ 150°C (each H-Bridge MOSFET)
  • 3.0 V and 5.0 V TTL / CMOS Logic Compatible Inputs
  • Overcurrent Limiting (Regulation) via Internal Constant-Off-Time PWM
  • Output Short Circuit Protection (Short to VPWR or Ground)
  • 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 < 50 µA (with Inputs Floating or Set to Match Default Logic States)
  • This product is included in NXP®'s product longevity program, with assured supply for a minimum of 15 years after launch
