MIC812

Microprocessor Reset Circuit with Manual Reset, Push-Pull Active-High Output, 4.0 V Thresh; ?Precision voltage monitor for 3V, 3.3V or 5V power supplies\n?/RESET remains valid with VCC as low as 1V\n?5μA typical supply current\n?140ms minimum reset pulse width available\n?Manual reset input\n?Available in 4-pin SOT-143 package;

The MIC811 and MIC812 are inexpensive microprocessor supervisory circuits that monitor power supplies in microprocessor based systems.The function of this device is to assert a reset if either the power supply drops below a designated reset threshold level or /MR is forced low. Several different reset threshold levels are available to accommodate 3V, 3.3V or 5V powered systems.The MIC811 has an active low /RESET output, while the MIC812 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 designed reset threshold level. Having a push-pull output stage, the MIC811/812 does not require a pull-up resistor at the output. The MIC811/812 comes in a 4-pin SOT-143 package.If a microprocessor voltage supervisor with an open-drain output stage is needed, see MIC6315.
