MAX4374FESD

Overview

The MAX4374FESD+ is a low-cost, micropower high-side current-sense supervisor featuring an integrated amplifier, comparator, and bandgap reference. It operates from a single +2.7V to +28V supply with a 50µA typical supply current. The device provides a voltage output proportional to the sense resistor voltage drop, eliminating external gain-setting resistors. It features a +50V/V gain version in a 14-pin SO package, specified for -40°C to +85°C operation.

Feature Summary

Integrated high-side current-sense amplifier with internal bandgap reference
Latching open-drain comparator output prevents oscillation during overcurrent events
Second comparator enables window-detection functionality for precise current monitoring
Voltage output design removes the need for external gain-setting resistors

Applications

Notebook computers
Portable/battery-powered systems
Smart battery packs and chargers
Cell phones
Power-management systems

Procurement Notes

Verify the specific suffix 'SD' corresponds to the 14-pin SO package configuration as listed in the official ordering information. Confirm RoHS compliance status via the '+' designation in the part number. Ensure the selected gain variant matches the required sensitivity for the target application circuit design.

Selection Notes

Select this component when high-side monitoring is required without interfering with the ground path. The +50V/V gain suits applications requiring moderate sensitivity. Verify that the external sense resistor power dissipation capabilities meet the maximum load current requirements to prevent drift or failure under overload conditions.

Part Context

This device belongs to the MAX4373/MAX4374/MAX4375 family of micropower current-sense supervisors. The MAX4374 specifically includes two comparators for window detection, distinguishing it from the single-comparator MAX4373. The 'F' suffix indicates the +50V/V gain configuration, while 'SD' denotes the 14-lead SO package type.
