Abstract
An integrated circuit includes: a control signal output; a pulse-width modulation (PWM) subsystem with a PWM input and a PWM output, the PWM output configured to provide PWM control signals; and configurable logic (CL) with a first CL input, a second CL input, and a CL output. The first CL input is coupled to the PWM output, the second CL input is adapted to receive a fault indicator. The CL output is coupled to the control signal output. The CL is configured to provide the PWM control signals to the control signal output unless the fault indicator indicates a fault.
