Two-rail supervisor in a SOT-23-6 footprint
The MAX6716UTSDD3-T is a multi-voltage supervisor from Analog Devices that monitors two independent supply rails with thresholds of 0.788 V and 2.925 V. It asserts an active-low reset output (push-pull, totem pole) when either voltage drops below its threshold, and holds reset for a minimum of 140 ms after both rails recover. Housed in a 6-pin SOT-23 package, it fits space-constrained boards where a single IC must supervise multiple voltage domains — common in mixed-voltage systems with a core logic rail and an I/O or memory rail.
What the threshold voltages mean for your board
The 140 ms minimum reset timeout gives the downstream processor time to stabilize after power-up before the reset de-asserts.
It is RoHS non-compliant per the manufacturer's declaration, so verify your assembly's RoHS exemption requirements before committing the BOM line. No single-source exposure — the part is widely stocked across multiple distributor inventories.
