Abstract
In an embodiment, an electronic circuit includes: a controller configured to produce a pulse-width-modulated (PWM) signal to control a first current of an electrical load; a redundant current measurement circuit configured to measure the first current and provide first and second current measurement signal; a monitor circuit coupled to the redundant current measurement circuit, the monitor circuit configured to assert a current monitor signal in response to the first and second current measurement signals being found to be matching with each other, wherein the monitor circuit is configured to: detect an absence of the asserted current monitor signal prior to expiry of a threshold time interval, and in response to detecting the absence of the asserted current monitor signal, force the controller to produce, prior to expiry of the threshold time interval, a first PWM signal pulse having a controlled duty-cycle.
