Product details

Active-high push-pull output — interface matching

Because the reset output is active high and push-pull, it drives the reset input of a processor or logic device that expects a high level during reset.

Lifecycle and compliance

The MAX812TEUS is listed as Active in production, so there is no last-time-buy or end-of-life risk for new designs today. One notable constraint: this part is RoHS non-compliant, which means it contains lead (Pb) and cannot be used in products destined for markets with RoHS exemption limits unless a specific exemption applies. For RoHS-required builds, look at the lead-free version of this family (the MAX812TEUS+ suffix, if available) or an alternative supervisor with the same threshold and output polarity. The part ships in a SOT-143-4 surface-mount package, which is a common footprint for voltage supervisors and easy to place in reflow assembly.

Frequently asked questions

Is MAX812TEUS active high or active low reset?

The MAX812TEUS has an active-high reset output. The reset signal goes high when the supply voltage drops below the threshold, and remains high for the timeout period after the supply recovers.

What is the reset timeout period of MAX812TEUS?

The reset timeout is a minimum of 140ms. This is the time the output stays asserted after the supply voltage rises above the threshold, ensuring the processor has time to stabilize.

Can I use MAX812TEUS as a replacement for MAX811TEUS?

No, the MAX812TEUS has an active-high reset output, while the MAX811TEUS has an active-low reset output. They are not pin-compatible or functionally interchangeable without a logic inversion on the reset line.

Is MAX812TEUS RoHS compliant?

No, the MAX812TEUS is listed as RoHS non-compliant. It contains lead and is not suitable for RoHS-required applications unless a specific exemption applies. For RoHS-compliant builds, consider the lead-free variant of this part (if available) or an alternative supervisor.
