Product details

140ms reset timeout — enough for most oscillators

The 140ms minimum reset timeout gives the processor's internal oscillator and PLL time to stabilize after power-up. If your MCU has a fast-starting internal oscillator, this is plenty; if you are using an external crystal with a slow startup, verify the crystal's startup time against 140ms.

Housed in a SC-70-4 surface-mount package, this part takes up minimal board space. The four pins are: ground, reset output, VCC, and a no-connect or manual-reset input depending on the variant.

Frequently asked questions

What is the reset timeout of MAX6384XS44D3?

The reset timeout is a minimum of 140ms. That is the time the reset output stays low after the supply voltage rises above the 4.38V threshold, giving the processor time to start up cleanly.

Is MAX6384XS44D3 pin compatible with other MAX6384 variants like MAX6384XS44D2?

Yes, the MAX6384XS44D3 shares the same SC-70-4 footprint and pinout as other MAX6384XS44 variants. The difference is the threshold voltage — the 'D3' suffix indicates a 4.38V threshold, while a 'D2' suffix would be a different threshold. You can swap them on the same board layout as long as the threshold matches your rail voltage.

What is an equivalent or replacement for MAX6384XS44D3?

Within the MAX6384 family, any part with the same package (SC-70-4) and the same threshold voltage (4.38V) is a direct functional replacement. The suffix 'XS44D3' encodes the package and threshold; a part like MAX6384XS44D2 would have a different threshold. Outside the family, look for a single-channel supervisor with a 4.38V threshold, active-low push-pull output, and 140ms reset timeout in a SC-70-4 package — many suppliers offer pin-compatible parts.
