POWER MANAGEMENT
General Description
Key Features
The IMP811/IMP812 are low-power supervisors designed to monitor voltage levels of 2.5V,3.0V, 3.3V and 5.0V power supplies in low-power microprocessor (µP), microcontroller (µC) and digital systems. Each fea-tures a debounced manual reset input. The IMP811/812 are improved drop-in replacements for the Maxim MAX811/812 with extended temperature specifications to 125°C. A reset signal is issued if the power supply voltage drops below a preset threshold and is asserted for at least 140ms after the supply has risen above the reset threshold. The IMP811 has an active-low output RESET that is guaranteed to be in the correct state for VCC down to 1.1V. The IMP812 has an activehigh output RESET.
