Product details

Dual-rail supervisor in a SOT-23-6

The MAX6829TWUT+ from Maxim Integrated is a dual ultra-low-voltage power supply monitor that tracks two independent voltage rails and asserts a single active-low reset output when either falls below its threshold. It monitors a 1.665 V threshold on one input and a 3.08 V threshold on the other. The push-pull, totem-pole output eliminates the need for an external pull-up resistor. The 140 ms minimum reset timeout gives the monitored rails time to stabilise.

No official replacement or second-source alternate is listed, so dual-sourcing would require qualifying a functionally equivalent supervisor from another vendor with matching thresholds and output type.

Frequently asked questions

What does the MAX6829TWUT+ monitor?

It monitors two voltage rails: one with a threshold of 1.665 V (typically a 1.8 V core supply) and one with a threshold of 3.08 V (typically a 3.3 V I/O supply). When either rail drops below its threshold, the active-low reset output is asserted for at least 140 ms after both rails recover.
