MAX4766AETA+

Overview

The MAX4766AETA+ is a single-channel programmable current-limit power switch IC designed for power distribution applications. It operates within a supply voltage range of 2.25V to 4.5V and supports an output current limit adjustable from 75mA to 1.5A. The device features a maximum run time of 17.5ms and a maximum retry time of 150µs. It is housed in a TDFN-8 EP surface-mount package with dimensions of 3mm x 3mm and a height of 0.80mm. The component functions reliably across an operating temperature range of -40°C to +85°C, providing robust protection for downstream loads.

Feature Summary

Programmable current limiting allows precise adjustment of fault protection thresholds between 75mA and 1.5A
Configurable retry behavior with selectable run and retry times for managing transient overcurrent events
Integrated thermal shutdown protects the device and load during sustained fault conditions

Applications

Power distribution networks requiring per-line current protection
Peripheral interface circuits needing controlled power sequencing
Embedded systems with multiple voltage rails requiring individual channel management

Procurement Notes

Verify that the specific suffix 'AETA+' matches the required pinout and thermal pad configuration for your PCB layout. Confirm that the programmable current limit settings align with your system's maximum load requirements. Ensure compatibility with the 2.25V to 4.5V input voltage range. Check for any regional distribution restrictions or obsolescence notices directly from Analog Devices before finalizing procurement plans.

Selection Notes

Select this component when a single-channel solution with fully programmable current limits is required. Compare against fixed-limit switches if flexibility is not needed. Consider the TDFN-8 package size constraints relative to available board space. Evaluate the thermal performance characteristics against the expected ambient temperature range and heat dissipation capabilities of the target application environment.

Part Context

The MAX4766 series belongs to Maxim Integrated's family of programmable current-limit switches. Variants such as MAX4766BETA offer different default configurations or pinouts. These devices are commonly used in industrial and consumer electronics where reliable power management and load protection are critical. The series provides a compact alternative to discrete MOSFET-based protection circuits.
