Product details

Monolithic current-sense front-end with comparator and reference

The MAX4373FEUA+T integrates a current-sense amplifier, comparator, and reference in an 8-uMAX/uSOP package.

What the integrated reference and comparator mean for your design

The on-chip comparator and reference set the overcurrent threshold with one external resistor divider. The open-drain output pulls to the logic rail voltage.

Package and footprint for layout review

The 8-uMAX/uSOP package has a 3.00 mm body width. The cut-tape option is available for prototype quantities.

Lifecycle and sourcing posture

The MAX4373FEUA+T carries an Active product status and is ROHS3 compliant. No end-of-life notices are in effect.

Frequently asked questions

What is the replacement for MAX4373FEUA+T?

There is no direct replacement announced by the manufacturer. The MAX4372 family is pin-compatible but lacks the on-chip comparator and reference, so it is not a functional substitute. For an exact drop-in, source the MAX4373FEUA+T through the RFQ process here.

What is the MAX4373FEUA+T used for?

It is used for current sensing and power management — for example, monitoring load current in a power-supply rail and generating an overcurrent alert when the sensed voltage exceeds the internal 1.2 V reference threshold.

MAX4373FEUA+T vs MAX4372 — what is the difference?

The MAX4373 integrates a comparator and 1.2 V reference on-chip; the MAX4372 is a current-sense amplifier only. If your design needs a threshold-detection output (overcurrent flag), the MAX4373 saves an external comparator and reference. If you only need an amplified analog output to an ADC, the MAX4372 is sufficient and costs less.
