MAX16946GUE/V+T

Overview

The MAX16946GUE/V+T is an automotive-grade Power Management IC (PMIC) designed for remote antenna systems. It integrates a current-sense amplifier, an LDO regulator, and a switch. The device operates on a supply voltage range of 4.5V to 18V with a typical supply current of 2.1mA. It supports an operating temperature range from -40°C to +105°C and holds AEC-Q100 qualification.

Feature Summary

• Integrates power distribution functions including a switch and LDO regulator within a single compact package.
• Includes built-in current-sense capabilities for monitoring load conditions in remote antenna applications.

Applications

• Remote antenna power management
• Automotive electronic control units
• Current-sensing load distribution

Procurement Notes

Verify the specific suffix 'GUE' against official Analog Devices documentation to confirm pinout and thermal pad configuration. Ensure the component meets AEC-Q100 grade requirements for your target automotive environment. Cross-reference the datasheet revision date to validate parameter consistency before finalizing procurement specifications.

Selection Notes

Select this PMIC when a combined solution for switching, regulation, and current sensing is required for automotive antenna modules. Consider the 16-TSSOP footprint for space-constrained designs. Validate that the 4.5V to 18V input range aligns with the vehicle's electrical system architecture.

Part Context

This part belongs to the Maxim Integrated automotive PMIC family, specifically tailored for distributed power architectures. It replaces discrete solutions by consolidating switch, LDO, and sense functions, reducing board area and component count in modern vehicle electronics.

Replacement Considerations

Consult the manufacturer's cross-reference guide for verified alternatives. Generic replacements may not match the integrated current-sense accuracy or AEC-Q100 automotive qualification standards required for this application.
