4-Pin µP Voltage Supervisor with Manual Reset

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.
