Product details

It is not qualified to AEC-Q100, so it is not the pick for under-hood automotive or engine-bay applications. For those, look at the automotive-graded siblings in the same family.

RoHS non-compliant — plan for it

That is fine for most industrial and military builds that carry a RoHS exemption, but if your product must ship into EU markets under the current RoHS directive without an exemption, you will need to source the RoHS-compliant version of this supervisor. The lead-bearing finish is actually preferred for high-reliability solder joints in thermal-cycling environments, so some buyers specifically request the non-compliant variant.

If you are filling a BOM line, this is a straightforward part to source without obsolescence risk.

Frequently asked questions

Is MAX825ZEXK-T active high or active low reset?

The MAX825ZEXK-T offers both Active High and Active Low reset outputs, selectable by the output configuration. The push-pull output can drive either polarity, so you can use it with processors that expect a high-going reset signal or those that expect a low-going reset signal.

What is the exact reset threshold voltage of MAX825ZEXK-T?

The reset threshold voltage is 2.32V. That is the voltage at which the supervisor asserts reset when the monitored rail drops below this level, and de-asserts reset after the rail rises above it and the timeout expires.

What is the reset timeout duration of MAX825ZEXK-T?

The reset timeout is a minimum of 140ms. The reset output remains asserted for at least 140ms after the supply voltage rises above the 2.32V threshold, giving the downstream processor time to complete its power-on initialization.

Can MAX825ZEXK-T replace the non-T variant MAX825ZEXK?

The MAX825ZEXK-T is a tape-and-reel packaged variant of the MAX825ZEXK. The die and electrical specifications are identical. The only difference is the shipping medium: the -T suffix indicates tape-and-reel packaging, while the non-T variant ships in tube or bulk. Functionally, they are interchangeable on the board.
