The 30µs typical reset timeout gives the downstream processor or FPGA enough time to complete its internal reset sequence after the supply stabilises. That is a short timeout — suitable for fast-starting microcontrollers and FPGAs that do not need a long delay before releasing the reset line.

Product details
Frequently asked questions
What is the reset timeout and threshold voltage for MAX6808UA46?
The reset timeout is 30µs typical, and the voltage threshold is 4.6V. The reset output is active-low, open-drain, so an external pull-up resistor is required.
Does MAX6808UA46 have a manual reset input?
The evidence does not indicate a manual reset input on this device. It is a simple power-on reset supervisor with a single monitored voltage and no additional manual reset pin.
Can MAX6808UA46 operate with a 3.3V supply?
The threshold voltage is 4.6V, which is intended for monitoring a nominal 5V rail. Operating this part on a 3.3V supply would keep the reset line asserted continuously because the supply would never reach the 4.6V threshold. It is not designed for 3.3V monitoring.
