The STM812SW16F: The output is push-pull, totem pole, and asserts Active High — meaning the reset pin goes high when the monitored voltage falls below threshold, and stays high through the timeout period. This polarity matches processors that expect a high-true reset input.
Package and temperature grade
Only one voltage is monitored, so this is a straightforward power-good watchdog for a single rail — not a sequencer or multi-voltage supervisor. The threshold is fixed at 2.93V, typical for 3.3V logic rails where a brownout below ~2.9V signals an unreliable supply.
