MIC811 Overview
Key Specifications
Package: SOT-143
Mount Type: Surface Mount
Pins: 4
Max Voltage (typical range): 5.5 V
Description
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.
Key Features
- Precision voltage monitor for 3V, 3.3V or 5V power supplies
- /RESET remains valid with VCC as low as 1V
- 5μA typical supply current
- 140ms minimum reset pulse width available
- Manual reset input
