Maxim MAX823TEUK 6µA Microprocessor Supervisory Circuits With Watchdog Timer And Manual Reset

Shenzhen Mingjiada Electronics Co., Ltd, as a world-renowned electronic component supplier, focuses on providing high-quality electronic component solutions for industrial automation, intelligent home appliances, new energy vehicles and other fields. We have been supplying MAX823TEUK ultra low power microprocessor monitor circuit for a long time.

Product Description Of MAX823TEUK

MAX823TEUK microprocessor (µP) supervisory circuits combine reset output, watchdog, and manual reset input functions in 5-pin SOT23 packages. The MAX823TEUK significantly improve system reliability and accuracy compared to separate ICs or discrete components. The MAX823TEUK is specifically designed to ignore fast transients on VCC.

Seven preprogrammed reset threshold voltages are available. MAX823TEUK devices have an active-low reset output, which is guaranteed to be in the correct state for VCC down to 1V. The MAX823TEUK also offers a watchdog input and manual reset input.
