Rated for -40°C to 125°C ambient, this part suits industrial motor drives, automotive under-hood modules, and outdoor telecom gear where the board sees wide thermal swings. ## Threshold and timeout — setting the reset window The adjustable/selectable reset timeout means you are not locked into a fixed delay. A small capacitor on the CT pin sets the period — useful when the downstream device needs a longer hold time to complete its internal power-up sequence or when a fast release is needed to meet a timing budget. ## Package and footprint Housed in a SOT-143-4 package (also TO-253-4), this is a four-lead surface-mount device. The SOT-143 footprint is compact and shares the land pattern with many small reset ICs. ## Lifecycle and compliance ROHS3 compliant, so it clears the REACH and RoHS requirements for EU-market equipment without an exemption certificate.","metaTitle":"MAX6423US22+T Simple Reset/Power-On Reset, 2.188V Threshold","metaDescription":"MAX6423US22+T is an active-low, open-drain reset IC from Analog Devices.
