5.0 A Throttle Control H-bridge

  The 33932 is a monolithic H-Bridge Power IC in a robust thermally enhanced package. The 33932 has two independent monolithic HBridge Power ICs in the same package. They are designed primarily for Automotive electronic throttle control, but are applicable to any lowvoltage DC servo Motor control application within the current and voltage limits stated in this specification. Each H-bridge in the 33932 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 peakcurrent 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 11 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 under-voltage, over-current, and over-temperature 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). FeaturesMC33932's datasheet is the same as MC33932
