摘要： A driver circuit and a diagnostic method are provided. The driver circuit includes a first voltage driver, a second voltage driver, and a microprocessor. The microprocessor generates a first pulse width modulated signal to induce the first voltage driver to output a second pulse width modulated signal to energize a contactor coil. The microprocessor sets a first diagnostic flag equal to a first value if a first filtered voltage value is greater than a first threshold value. The microprocessor sets a second diagnostic flag equal to a second value if a first filtered current value is less than a threshold value. The microprocessor stops generating the first pulse width modulated signal to de-energize the contactor coil if the first and second diagnostic flags are set equal to the first and second values, respectively.

摘要： A driver circuit and a diagnostic method are provided. The circuit includes a first voltage driver having a first output line electrically coupled to a main contactor coil of a main contactor. The circuit further includes a microprocessor that measures a first voltage on a first voltage feedback line if the main contactor coil is not energized. The microprocessor measures a second voltage on a second voltage feedback line if the main contactor coil is not energized. The microprocessor sets a status flag equal to a fault condition value if the first voltage is greater than a threshold voltage value. Also, the microprocessor sets the status flag equal to the fault condition value if the second voltage is greater than the threshold voltage value.
