MAX4845ELT+TG05

Specialized ICS Overview

The MAX4845ELT+TG05 is an overvoltage protection controller designed to safeguard low-voltage systems against high-voltage faults up to 28V. It features a preset overvoltage trip level of 5.8V and utilizes an internal charge pump to drive external n-channel FETs without requiring external capacitors. The device enters a low standby current mode (10µA) when input voltage drops below the undervoltage lockout threshold. It operates within a temperature range of -40°C to +85°C and is housed in a compact 6-pin µDFN package.

Specialized ICS Feature Summary

• Preset 5.8V overvoltage trip level for precise system protection
• Internal charge pump eliminates need for external capacitors
• Low standby current of 10µA during undervoltage lockout
• Integrated FLAG indicator for overvoltage fault detection

Specialized ICS Applications

• Cell Phones
• Digital Cameras
• Media Players

Specialized ICS Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific lot traceability requirements relevant to your manufacturing standards before finalizing procurement orders.

Specialized ICS Selection Notes

Select this model specifically for its 5.8V overvoltage threshold. Ensure the design accommodates the 6-µDFN (1.5x1mm) footprint. Verify that the external n-channel FET selected is compatible with the internal charge pump drive capability for optimal switching performance.

Specialized ICS Part Context

This component belongs to the MAX4843–MAX4846 family of overvoltage protection controllers. While sharing similar packaging and core functionality, each variant differs primarily in its preset overvoltage trip level, allowing designers to choose the specific voltage threshold required for their target application circuitry.

Specialized ICS Replacement Considerations

Direct replacements include other members of the MAX484x family such as the MAX4843, MAX4844, or MAX4846, provided the different preset trip voltages align with the system requirements. Ensure pin compatibility and thermal characteristics are reviewed when substituting.
