KIT33932VWEVBE评估板用于评估MC33932的特性，MC33932是散热增强型封装的单片电路H桥功率IC。The 33932 has two independent monolithic H-Bridge Power ICs in the same package. They are designed primarily for automotive electronic throttle control, but are applicable to any low-voltage 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 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 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.
