Product details

The Maxim Integrated MAX6458UKD0C+T is a Simple Reset/Power-On Reset IC that monitors a single supply voltage and asserts a reset signal when the voltage drops below a user-adjustable threshold. The active-low, open-drain output can be pulled up to any voltage independent of the monitored rail, making it suitable for mixed-voltage systems. With a typical reset timeout of 50 µs, the part recovers quickly once the supply returns above threshold. The SOT-23-5 package fits compact PCB layouts in industrial controls, automotive ECUs, and portable equipment where reliable power-on reset is required.

Threshold adjustability — why it matters for your rail

The open-drain output allows the reset signal to be pulled up to the logic voltage of the downstream microcontroller or FPGA, even if that differs from the monitored supply.

There is no last-time-buy or obsolescence risk for this order code.

Frequently asked questions

Is MAX6458UKD0C+T obsolete or still active?

The MAX6458UKD0C+T is listed as Active with ROHS3 compliance. There is no indication of discontinuation or last-time-buy.

Does MAX6458UKD0C+T have an open drain or push-pull output?

The output is open drain (open collector), which allows the reset signal to be pulled up to any voltage level independent of the monitored supply rail.

What is the reset timeout of MAX6458UKD0C+T?

The typical reset timeout is 50 µs. This short delay ensures the system recovers quickly after a supply dip or brownout.

Is MAX6458UKD0C+T compatible with 3.3V systems?

Yes. The adjustable threshold can be set to monitor a 3.3 V rail, and the open-drain output can be pulled up to 3.3 V logic. The -40°C to 125°C range covers typical industrial and automotive 3.3 V applications.
