Product details

What this supervisor does — and what it doesn't

The reset output is active high, push-pull. That means the pin goes high when the monitored voltage is out of tolerance. If your processor expects an active-low reset (the more common case), you'll need an inverter or a different part. The push-pull output drives the reset line directly without an external pull-up resistor. Temperature range spans -40°C to 125°C. The SC-70-4 package is small.

Lifecycle and compliance

RoHS non-compliant, so if your BOM requires RoHS, this part won't pass. For leaded assemblies or legacy builds where RoHS exemption applies, it's still a viable choice.

Frequently asked questions

Is MAX6385XS44D5 obsolete or EOL?

No. The lifecycle status is Active per the manufacturer's record. No end-of-life notice has been issued.

What is the reset timeout of MAX6385XS44D5?

The reset timeout is a minimum of 280ms. That's the time the reset output stays asserted after the supply rises above the 4.38V threshold.

Is MAX6385XS44D5 compatible with 3.3V microcontroller reset inputs?

No. The threshold is 4.38V, designed for a 5V rail. On a 3.3V supply the reset would be asserted continuously. Use a supervisor with a threshold below 3.3V for 3.3V systems.

Is MAX6385XS44D5 equivalent to MAX809 or other reset ICs?

Not directly. The MAX809 has an active-low, open-drain output and a different threshold range. The MAX6385XS44D5 is active-high, push-pull. They are not pin-compatible or function-compatible without a logic inversion.
