MAXIM INTEGRATED / ANALOG DEVICES MAX825TEUKT Microprocessor Supervisory Circuit

The MAX825TEUK+T is a microprocessor supervisory circuit available in a 5-pin SOT-23 package. It includes a watchdog timer and manual reset feature, designed to ensure the microprocessor starts in a known state and to prevent code execution errors during power-up, power-down, and brownout conditions. The device is robust against fast transient voltage changes, enhancing system reliability and accuracy compared to using separate ICs or discrete components. It supports a supply voltage range from 1.2V to 5.5V and operates over a temperature range of -40°C to 125°C. The circuit provides precise monitoring for +2.5V, +3V, +3.3V, and +5V power supplies, with a reset threshold voltage of 3.08V. It features a manual reset input, an active-high reset output, and fully specifies over the entire temperature range. The power-on reset duration is 200ms, and the reset remains valid down to VCC = 1V. It offers immunity to power supply transients and does not require external components for watchdog or reset functions. Suitable applications include system monitoring, portable devices, and automotive systems.
