The MIC1815 is a Microprocessor Reset Circuit from Micrel, it monitors the power supply in microprocessor based systems and generates a reset signal when the supply voltage drops below a pre-determined reset threshold voltage. There are a number of different reset threshold voltages available to accommodate 10% or 20% drop in 3.3V powered systems. The MIC1815 has a low-level RESET output. The reset output is guaranteed to remain asserted for a minimum of 100ms after VCC has risen above the designated reset threshold level. The MIC1815 is available in a 3-lead SOT-23 package.
The Infinite Bandwidth MIC1815 is an inexpensive microprocessor supervisory circuit designed to monitor power supplies in microprocessor-based systems. It asserts a reset if the power supply drops below a designated threshold level, ensuring the microprocessor resets properly after a power failure. The device is available with reset thresholds for 10% or 20% drops in 3.3V systems and comes in a 3-pin SOT-23 package requiring no external components.
