The MAX811SEUS+T with Supervisory Circuits 4-Pin uP Voltage Monitors with Manual Reset Input, manufactured by Analog Devices, is a voltage monitor used to provide cost effective voltage detection and system reset for microprocessors and digital logic circuits. It features a manual reset input, low supply current, and an active-low reset output, allowing it to provide power-on reset functionality. The supply voltage range is +3V to +6V, providing a 2.5V preset voltage threshold which is ideal for monitoring under-voltage and over-voltage conditions. It is an ideal solution for system controllers, microprocessor-based systems, and digital logic applications.
