Product details

150ms minimum reset timeout

The 150ms minimum reset timeout holds the processor in reset after the supply returns above the threshold. That window is long enough for most oscillators and PLLs to lock and for bulk capacitance to charge, but short enough that the system does not linger in reset unnecessarily. If your design requires a longer delay for a slow-start power supply or a specific power-up sequence, you may need an external timer or a different reset IC with a programmable timeout.

Lifecycle and sourcing

It is ROHS3 compliant.

Frequently asked questions

What is the reset timeout of MAX6466XR45+T?

The reset timeout is 150ms minimum. After the monitored voltage rises above the 4.5V threshold, the output stays low for at least 150ms before releasing.

Is MAX6466XR45+T active low?

Yes, the reset output is active low. The open-drain output pulls low when the supply drops below the threshold and releases (goes high-impedance) after the timeout when the rail is stable.
