Product details

65-V window supervisor with dual 0.8 V thresholds

The Texas Instruments TPS37A010122DSKR is a voltage detector that monitors two independent voltage rails against 0.8 V thresholds each and asserts an active-low reset when either rail drifts outside the window. The open-drain output lets you wire-OR multiple supervisors or level-shift to any logic supply up to the absolute maximum.

Reset timeout and output architecture

The reset timeout is 100 µs maximum — unusually fast for a supervisor. That means the reset de-asserts within 100 µs of the monitored voltage returning inside the window. For systems that need to restart quickly after a brownout (e.g., a motor controller recovering from a load dump), this avoids the several-hundred-millisecond delay typical of most reset ICs.

The 10-WSON (2.5x2.5) package with exposed pad requires a thermal-via stitch under the pad for heat sinking — without it the junction temperature climbs faster at high input voltage and continuous operation. Surface-mount assembly with standard reflow profile; MSL rating per the TI label.

Frequently asked questions

How do I use TPS37A010122DSKR as a window detector?

The TPS37A010122DSKR monitors two voltages against 0.8 V thresholds internally. For a window detector on a single rail, connect the rail through a resistor divider to both sense inputs — one resistor tap sets the undervoltage threshold at 0.8 V, the other tap sets the overvoltage threshold at 0.8 V. The active-low open-drain output asserts when the rail is outside either window boundary. The 100 µs max reset timeout means the output de-asserts quickly once the rail re-enters the window.
