Abstract

The invention discloses a processing method of a drive fault feedback signal and a circuit. The processing method of the drive fault feedback signal comprises acquiring the drive feedback signal by a programmable logic device, detecting a pulse signal in the drive feedback signal by the programmable logic device, detecting duration time of the pulse signal by the programmable logic device, determining whether the duration time meets a preset condition by the programmable logic device, and determining the pulse signal to be the drive fault feedback signal when the programmable logic device determines that the duration time does not meet the preset condition. Through the processing method and the circuit, the problem that a pure hardware circuit has the limited processing ability to the drive fault feedback signal in the prior art is solved.

Description

technical field [0001] The invention relates to the field of transistors, in particular to a processing method and circuit for driving fault feedback signals. Background technique [0002] At present, in the related art, most of the driving fault feedback processing circuits are hardware circuits. For example, a drive fault feedback processing circuit is provided in the related art, which is a pure hardware circuit, which includes: drive fault feedback signal processing circuit, pulse drive processing circuit, NAND gate circuit, drive selection circuit and fault latch circuit. Among them, the pulse drive signal processing circuit is used to receive and process the pulse drive signal; the drive selection circuit is used to output the NAND signal output by the NAND gate circuit to the fault latch circuit when the drive fault feedback signal is a pulse signal, and When the drive fault feedback signal is a high-low level signal, the signal output by the drive fault feedback si...
