MIC809 Overview
The MIC809 and MIC810 are inexpensive microprocessor supervisory circuits that monitor power supplies in microprocessor-based systems. The function of these devices is to assert a reset if the power supply drops below a designated reset threshold level. Several different reset threshold levels are available to acmodate 3V, 3.3V or 5V powered systems.
MIC809 Key Features
- Precision voltage monitor for 3V, 3.3V, or 5V power supplies
- /RESET remains valid with VCC as low as 1.4V for SOT-23 packaged part
- /RESET remains valid with VCC as low as 1V for SC70-packaged part
- Typically less than 15μA supply current for SOT-23 packaged part
- 5µA (typical) supply current for SC70-packaged part
- 140ms (minimum) reset pulse widths available
- Available in 3-pin SOT-23 and SC-70 package
