MAXIM INTEGRATED / ANALOG DEVICES MAX6421XS29T voltage supervisor

The MAX6421XS29T is a low-power microprocessor reset circuit in a 4-pin SC-70 package. It monitors system voltage levels from 1.6V to 5V and asserts a reset signal when the supply voltage falls below its threshold. The reset output is active-low and remains asserted for a programmable timeout period after VCC rises above the threshold, with the timeout adjustable via an external capacitor. The device features a reset threshold voltage of 2.925V, operates over a temperature range of -40°C to 125°C, and has a low quiescent current of approximately 1.6µA at VCC ≤ 2V. It is suitable for use in battery-powered systems, embedded controllers, and portable devices, providing reliable system reset monitoring.
