Product details

Package and footprint

The MAX812LEUS comes in a SOT-23-4 surface-mount package (also referred to as TO-253-4).

Temperature grade and environment

Rated for -40°C to 85°C ambient, the MAX812LEUS covers industrial environments — factory automation, telecom cabinets, outdoor instrumentation, and HVAC controllers. It is not qualified to AEC-Q100, so it is not the first choice for under-hood automotive or engine-bay applications. For a 5V rail in a control cabinet or a base station power supply, the temperature range is sufficient.

Lifecycle and sourcing

The part is RoHS non-compliant. Verify your assembly line's exemption status if you require RoHS compliance.

Frequently asked questions

What is the exact reset threshold voltage of MAX812LEUS?

The reset threshold voltage is 4.63V, suitable for monitoring a nominal 5V supply rail.

Is MAX812LEUS active high or active low reset output?

It goes high when the monitored voltage drops below the threshold and stays high for the 140ms timeout after the voltage recovers.

What is the reset timeout of MAX812LEUS?

The reset timeout is 140ms minimum. This ensures the supply and oscillator stabilize before the processor is released from reset.
