Dual-rail watchdog in a six-pin package
The MAX6721UTLTD3-T: The reset output is open-drain, so it can be wire-ORed with other supervisor outputs on the same reset line, and the 140 ms minimum timeout holds the reset long enough for the downstream rails and oscillators to stabilise after both voltages return within tolerance.
Package and temperature fit for production boards
Housed in a SOT-23-6 package with a surface-mount footprint, the part fits into compact layouts where board space is tight — the same 6-pin pattern used by many single-voltage supervisors, so a layout already designed for a SOT-23-6 supervisor can accept this dual-channel part without a board spin.
Note that the part is listed as RoHS non-compliant, so it does not carry the lead-free / RoHS marking — confirm your assembly's exemption or waiver before specifying this order code for a RoHS-required BOM line.
