MAX4375FESD

Overview

The MAX4375FESD+ is a low-cost, micropower high-side current-sense supervisor integrating a current-sense amplifier, bandgap reference, and comparator. It features a +50V/V gain version with a 14-pin SO package. The device operates from a single +2.7V to +28V supply, consuming 50µA. It supports a 0 to +28V input common-mode range independent of the supply voltage. The comparator output is latching to prevent oscillation during overcurrent events.

Feature Summary

• Integrates a high-side current-sense amplifier, internal bandgap reference, and latching comparator for simplified monitoring.
• Features a +50V/V fixed gain configuration suitable for specific battery pack sensitivity requirements.
• Provides a latching open-drain output that eliminates oscillation during overcurrent shutdown conditions.

Applications

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

Procurement Notes

Verify the exact suffix 'FESD' corresponds to the +50V/V gain and 14-pin SO package variant. Confirm lead-free/RoHS compliance status indicated by the '+' symbol in ordering codes. Ensure the operating temperature range matches the -40°C to +85°C specification required for the application environment.

Selection Notes

Select this part when a fixed +50V/V gain is required for high-side current sensing. It is appropriate for systems needing integrated overcurrent protection with a latching output. Consider the 14-pin SO package constraints and the 0 to +28V common-mode range compatibility with the target power supply architecture.

Part Context

This component belongs to the MAX4373/MAX4374/MAX4375 family of micropower current-sense supervisors. The MAX4375 specifically includes two comparators for window detection functions. The 'F' designation indicates the +50V/V gain option, while 'SD' denotes the 14-pin Small Outline package type within the Maxim Integrated product line.
