ETC811 - Microprocessor Reset

General Description

The MIC811 and MIC812 are inexpensive microprocessor supervisory circuit that monitors 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.

Key Features

  • Precision voltage monitor for 3V, 3.3V or 5V power supplies.
  • /RESET remains valid with VCC as low as 1.4V.

MIC811/812 Micrel MIC811/812 Microprocessor Reset Circuits Final Information General Description The MIC811 and MIC812 are inexpensive microprocessor supervisory circuit that monitors 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. The MIC811/812 comes in a 4-pin SOT-143 package.
