The Analog Devices MAX6841FUKD3+ is a Simple Reset/Power-On Reset IC that monitors a single voltage rail and asserts a reset signal when the supply drops below its 1.05V threshold. It delivers both active-high and active-low push-pull outputs, so it can drive reset inputs of either polarity without an external inverter. This part is used in low-voltage core monitoring for MCUs, FPGAs, and DSPs in industrial control, telecom infrastructure, and embedded systems where the monitored rail is around 1.05V.
The 1.05V threshold monitors a single voltage rail.
Reset timeout and output drive
The 150µs typical reset timeout is a relatively short delay — suitable for fast-booting processors that do not need a long hold-off after power-good. Both active-high and active-low signals are available from the same device, which simplifies board layout when the processor expects one polarity and a peripheral expects the other.
Housed in a SOT-23-5 package, this part takes minimal board area and is suited for dense PCB layouts.
