IMP812

ISO 9001 Registered IMP811, IMP812 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. The reset comparator is designed to ignore fast transients on VCC. Low power consumption makes the IMP811/ IMP812 ideal for use in portable and batteryoperated equipment. Available in a compact 4-pin SOT143 pack...
