If your board lives in a motor drive enclosure, an outdoor telecom cabinet, or an engine bay ECU, this supervisor will hold the reset line through the temperature swings without drifting the threshold. Packaged in a SOT-23-6, it fits on tight PCB layouts where board space is at a premium. The open-drain output lets you wire-OR the reset signal with other supervisors or a manual reset button — just add a pull-up resistor to the logic supply rail.

Frequently asked questions
What is the reset timeout of MAX6343TUT+T?
The reset timeout is a minimum of 100ms. After the monitored voltage rises above the 3.08V threshold, the reset output stays low for at least 100ms before releasing.
Is MAX6343TUT+T active low?
Yes, the reset output is active low. The open-drain output pulls low when the supply drops below the threshold and releases high-impedance after the timeout.
