Product details

The Analog Devices MAX14523AATA+T is a current switch IC — a precision electronic fuse that monitors current through an external sense resistor and opens the load path when the set threshold is exceeded. It is not a linear regulator or a simple PTC; it latches off or auto-retries depending on the configuration, giving you deterministic overcurrent protection down to a ±10% accuracy window.

Setting the current limit — the external resistor

The output current is adjustable via a single external resistor connected to the SET pin. The resistor value programs the trip threshold.

Frequently asked questions

What is the function of MAX14523AATA+T?

It is a current switch — an electronic overcurrent protector that opens the load path when current exceeds a user-set threshold, with ±10% accuracy on the trip point.

Can MAX14523AATA+T be used for overcurrent protection?

Yes, that is its primary function. It monitors current through an external sense resistor and switches off the load when the set threshold is exceeded, providing overcurrent protection with ±10% accuracy.

How to configure MAX14523AATA+T for a specific current limit?

Connect an external resistor between the SET pin and ground. The resistor value determines the trip threshold; the datasheet provides the calculation formula. The output current is adjustable, and the ±10% accuracy applies to the programmed limit.
