MAX4987AEETA+TG05

Specialized ICS Overview

The MAX4987AEETA+TG05 is an overvoltage protection controller with integrated ESD protection for USB data lines. It features a low 100mΩ (typ) internal nFET switch that protects systems against voltage faults up to +28V. The device includes a preset 6.15V overvoltage threshold and a 2.55V undervoltage lockout threshold. It offers ±15kV HBM ESD protection on CD+/CD- pins and supports high-speed USB 2.0 signals with 3pF capacitance. The component operates in the -40°C to +85°C range within an 8-TDFN package.

Specialized ICS Feature Summary

• Input voltage protection up to +28V with 100mΩ (typ) Ron internal nFET switch
• Integrated 1.5A minimum current-limit protection with 30ms autoretry mode
• Low-capacitance (3pF) ESD protection for USB data lines supporting USB 2.0
• Preset thresholds: 6.15V OVLO and 2.55V UVLO for MAX4987AE variant

Specialized ICS Applications

• Cell Phones
• Media Players

Specialized ICS Procurement Notes

Verify the specific suffix 'TG05' against official manufacturer documentation, as standard datasheets list 'ETA+'. Confirm the package type is 8-TDFN (2x3mm) with exposed pad. Ensure the operating temperature range meets requirements of -40°C to +85°C. Check for lead-free compliance indicated by the '+' symbol in the part number.

Specialized ICS Selection Notes

Select the MAX4987AE variant for a 2.55V undervoltage lockout threshold; choose MAX4987BE for a 4.2V threshold. Both share the same 6.15V overvoltage threshold. Ensure the application requires USB data line protection with low capacitance (3pF). Verify that the input voltage stays within the 2.2V to 28V range for proper operation.

Specialized ICS Part Context

This component belongs to the MAX4987 series of overvoltage protection controllers designed for portable electronics. It integrates an nFET switch, charge pump, and ESD protection into a compact 2mm x 3mm TDFN package. The series is optimized for protecting USB interfaces in battery-powered devices from voltage transients and electrostatic discharge events.
