Product Summary
The IMP811SEU is a 4-Pin μP Voltage Supervisor with Manuall Reset. The IMP811SEU is 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 IMP811SEU is improved drop-in replacements for the Maxim IMP811SEU with extended temperature specifications to 105℃. The applications of the IMP811SEU include Computers and controllers, embedded controllers, Battery operated systems, Intelligent instruments, Wireless communication systems, PDAs and handheld equipment.
