MAX4374FESD+T

Overview

The MAX4374FESD+T is a low-cost, micropower high-side current-sense supervisor integrating a current-sense amplifier, comparator with latching output, and bandgap reference. It operates from a single +2.7V to +28V supply with a typical supply current of 50µA. The device features a +50V/V gain version, a 0 to +28V input common-mode range independent of supply voltage, and an operating temperature range of -40°C to +85°C. It is housed in a 14-pin SO package.

Feature Summary

• Integrates a high-side current-sense amplifier, internal comparator with latching output, and bandgap reference for simplified monitoring.
• Features a second comparator to enable window-detection functions for precise current threshold management.
• Provides a voltage output that eliminates the need for external gain-setting resistors.
• Operates with a 0 to +28V common-mode input range independent of the supply voltage.

Applications

• Notebook Computers
• Portable/Battery-Powered Systems
• Smart Battery Packs/Chargers
• Cell Phones
• Power-Management Systems

Procurement Notes

Verify the specific suffix 'F' indicates the +50V/V gain configuration and 'SD' denotes the 14-pin SO package. Confirm the '+' suffix ensures lead-free and RoHS compliance. Cross-reference the manufacturer's ordering information to ensure compatibility with the required thermal and electrical specifications for your design.

Selection Notes

Select this component when a dual-comparator window detection capability is required alongside high-side current sensing. The +50V/V gain is suitable for applications requiring moderate amplification of the sense resistor voltage. Ensure the application utilizes a single supply within the 2.7V to 28V range and requires an extended industrial temperature rating.

Part Context

This part belongs to the MAX4373/MAX4374/MAX4375 family of low-cost, micropower high-side current-sense supervisors. The MAX4374 variant specifically includes two comparators for window detection, distinguishing it from the single-comparator MAX4373 and the complementary-window MAX4375. All variants share the same core amplifier architecture and power characteristics.
