Abstract
A semiconductor circuit is disclosed, comprising: a processor; a supply-voltage terminal arranged to receive a supply voltage; an out-of-range-voltage-detection circuit, coupled to the supply-voltage terminal and configured to output a voltage-out-of-range indicator in response to detecting that the supply voltage is out-of-range; a PWM signal generator configured to generate a PWM signal; a power-on-reset request terminal arranged to output the PWM signal during a normal operation of the processor; and logic circuitry between the signal generator and the POR request terminal and configured to modify the PWM signal in response receiving the voltage-out-of-range indicator. A microcontroller circuit incorporating such a semiconductor circuit, and a PMIC circuit for use in conjunction, are also disclosed.
