Circuit safely applies power to ICs

Posted on Jun 27, 2012

Supervisory circuits normally monitor a microprocessor`s supply voltage, asserting reset to the IC during power-up, power-down, and brownout. In this way, the circuit ensures that the supply voltage is stable before the microprocessor boots, thus preventing code-execution errors. Many analog and digital ICs also need a well-behaved start-up of their supply to avoid latch-up and logic-state errors.
