The Evaluation Kit for the 33932, which is a monolithic H-Bridge Power IC in a robust thermally enhanced package. 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. This Evaluation kit may be used with the KITUSBSPIDGLEVME.
