MAX16946GTE/V+

Overview

The MAX16946GTE/V+ is an automotive-grade power distribution IC featuring integrated remote antenna sensing, current sense, and LDO/switch capabilities. It operates within a supply voltage range of 4.5 V to 18 V and supports a maximum load current of 300 mA. The device includes programmable soft-start with a maximum run time of 10 ms and a maximum idle time of 420 µs. It is housed in a TQFN-16 EP package and is qualified under AEC-Q100 standards for operation between -40°C and +105°C.

Feature Summary

• Integrates remote antenna detection functionality for automotive applications
• Provides precise current sensing capabilities for load monitoring
• Combines low-dropout regulator and switch outputs in a single package

Applications

• Automotive infotainment systems requiring protected power distribution
• Vehicle body control modules needing antenna switching
• Industrial equipment with high-reliability power management requirements

Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm exact thermal and electrical specifications. Confirm AEC-Q100 qualification status for your target application environment. Ensure the TQFN-16 EP footprint matches your PCB layout constraints. Cross-reference the datasheet revision date to ensure compatibility with your design timeline.

Selection Notes

Select this component when simultaneous antenna control, current monitoring, and regulated power delivery are required in space-constrained designs. The integrated nature reduces external component count compared to discrete solutions. Consider the 300 mA limit and thermal dissipation characteristics relative to your expected load profile and ambient temperature conditions.

Part Context

This part belongs to the MAX16946 series of power distribution ICs designed for robust automotive environments. It consolidates multiple power management functions typically handled by separate components, simplifying system architecture. The series emphasizes reliability and integration for critical vehicle subsystems.

Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Generic equivalents may not match the specific remote antenna or current-sense integration features.
