The invention discloses a motor controller circuit system and a motor controller, and is applied to driving fault detection of the motor controller, the circuit system comprises a driving detection circuit, the driving detection circuit is respectively connected with a main controller and a driving circuit, and through the driving detection circuit, a first PWM signal sent by the main controller is firstly read; a second PWM signal output by the driving circuit is read back; secondly, comparing the first PWM signal with the second PWM signal and outputting a fault diagnosis result; and then, according to a fault diagnosis result, a driving circuit fault indication signal is output to the main controller, so that a safety state is output through the main controller. According to the technical scheme, on one hand, the fault of the driving chip can be diagnosed, and on the other hand, fault conditions such as failure of the driving circuit can be diagnosed, so that the coverage rate of fault diagnosis of the driving circuit is improved, and the safety integrity level of the automobile ASILD is further improved.
