The MAX824TEUK+T Supervisory Circuit manufactured by Analog Devices is a 5-pin MPU supervisor that provides under-voltage protection, power-on reset, and real-time clock pin monitoring. It is designed to enable a wide variety of microprocessors and microcontroller systems to automatically monitor and reset themselves, in the event of a power glitch or sudden degradation of power. The MAX824TEUK+T features a wide operating voltage range from 1.5V to 5.5V and an adjustable under-voltage threshold of 1.3V to 4.5V. It offers an active low reset signal, an adjustable reset timeout, and an integrated voltage monitor for keeping track of real-time clock (RTC) circuits. Furthermore, it can be used with a range of typical supply current and reset time delays, and includes an extra low-battery detect output. It is ideal for applications such as power-on reset, voltage monitoring, and reset generation.
