The reset timeout is 100µs maximum — that's the delay after the rail returns above threshold before the output de-asserts. It's fast enough to prevent nuisance resets from short glitches while still catching a genuine brownout before the downstream logic corrupts state.
The TPS38 family shares the same base design across threshold variants.
Yes, it is AEC-Q100 qualified, which means it has passed the automotive reliability stress tests for temperature cycling, ESD, latch-up, and extended life. The operating temperature range is -40°C to 125°C junction.
It is designed for automotive ECU power-supply monitoring — watching dual 0.8V core rails in engine control units, transmission controllers, ADAS domain controllers, and similar under-hood electronics where a brownout or overvoltage must trigger a system reset.
It is a Voltage Detector with an Active-Low reset output. The output is Open Drain or Open Collector, so it can be wire-ORed with other fault signals.
