Active production — two-rail supervisor in SOT-23-6
The MAX6716UTTGD3-T is an active-production multi-voltage supervisor from Analog Devices, monitoring two supply rails with thresholds at 1.11 V and 3.075 V. It asserts an active-low reset when either rail drops below its threshold, holding reset for a minimum of 140 ms after all rails recover.
Thresholds and reset timing for dual-rail sequencing
The two monitored thresholds — 1.11 V for the low rail and 3.075 V for the high rail — cover common core and I/O supply pairs in systems with a 1.2 V core and 3.3 V I/O. The 140 ms minimum reset timeout gives the downstream loads time to stabilize after the rails come up, avoiding spurious power-on resets from supply ringing. The push-pull, totem-pole output drives the reset line without an external pull-up resistor, simplifying the BOM by one component per supervisor channel. Active-low reset polarity matches the convention for most MCUs, FPGAs, and SoCs.
Package and temperature grade for board integration
Housed in a 6-pin SOT-23-6 package, the MAX6716UTTGD3-T occupies minimal board area and fits into dense mixed-signal layouts.
