The IMP811/IMP812 are low-power supervisors designed to monitor

voltage levels of 3.0V, 3.3V and 5.0V power supplies in low-power

microprocessor (μP), microcontroller (μC) and digital systems. Each features a debounced manual reset input. The IMP811/812 are improved

drop-in replacements for the Maxim MAX811/812 with extended

temperature specifications to 105°C
