Microchip Voltage Supervisor 2.63V max., MIC811RUY-TR

The microchip microprocessor reset circuit is an expensive and has supervisory circuit that monitor power supplies in microprocessor based systems. T he function of this device is to asset if either the power supply drops below a designated reset threshold level is forced low. the microprocessor has an active reset output, while the microprocessor offers an active high reset output. The reset output is guaranteed to remain asserted for a minimum of 140ms after vcc has risen above the designated reset threshold level. Having a push-pull output stage . If a microprocessor voltage supervisor with an open-drain output stage is needed.

140ms minimum reset pulse width available
The precision voltage monitor for 3v, 3.3v or 5v power supplies
It is a manual reset input
Reset remains valid with VCC as low as 1v
