Three-rail supervisor for ATX and industrial PSUs
The TPS3514N: It asserts a common Active Low reset signal (open-drain output) whenever any monitored rail falls below its threshold, and holds reset for a minimum of 200 ms after all rails return to tolerance. This window gives the downstream regulators and the main system controller time to stabilize before the reset releases.
Industrial temperature grade and through-hole package
The 14-DIP (0.300", 7.62 mm) through-hole package simplifies prototyping and hand-assembly, and the 200 ms reset timeout is fixed, so no external capacitor is needed to set the delay. The open-drain output lets multiple supervisors share a common reset line through a pull-up resistor.
ROHS3 compliant. The part is sourced to order against your BOM quantity — confirm the 14-DIP footprint and the 3.3 V / 5 V / 12 V threshold match your rail voltages before committing.
