The output is push-pull, totem pole, and the reset polarity is Active High. That is the key fit check: most supervisors in this class assert a low reset, so this part only goes into designs where the processor or peripheral expects a high-going reset pulse. If you are swapping a supervisor on a board that uses a low-true reset, the STM706M6F (active low, same pinout) is the drop-in. Not rated for under-hood automotive or downhole, but solid for most IP54-ish enclosures.
Package and mounting – field-swap realities
8-SOIC, 3.90 mm body width, surface mount. That is a standard footprint you can rework with a hot-air station or a decent soldering iron and flux — no QFN hidden pads, no BGA alignment. Marking on the top side is legible under a loupe; orientation is obvious from the pin-1 bevel. No special storage beyond standard moisture-sensitive-device handling — bake before reflow if the bag seal is broken.
Lifecycle and sourcing – no LTB clock ticking
That means no last-time-buy notice looming, no end-of-life scramble.
Active High reset – the gotcha that trips field swaps
The reset polarity is Active High. That is the single spec that separates this part from the more common active-low supervisors. If your board uses a pull-up on the reset line expecting a low-true signal, dropping in this part will hold the processor in reset permanently.
