MAX16984SACIL/V+T

Overview

The MAX16984SACIL/V+T is an automotive-grade integrated power management solution combining a high-current step-down converter with USB-C protection and emulation capabilities. The buck converter delivers up to 2.5A output current at a fixed 5V, operating within a 4.5V to 28V input range. It features an adjustable switching frequency from 220kHz to 2.2MHz. The device includes a USB host charger adapter emulator and comprehensive port protection. It operates across an extended temperature range of -40°C to +125°C and holds AEC-Q100 qualification. The unit is housed in a compact 28-lead LFCSP package measuring 4mm x 4mm.

Feature Summary

• Integrates a 2.5A synchronous buck converter with adjustable switching frequency for flexible design optimization.
• Includes built-in USB host charger adapter emulator functionality to support standard USB communication protocols.
• Provides integrated USB port protection circuitry to safeguard against electrical faults and surges.
• Qualified for automotive applications under AEC-Q100 standards with extended industrial temperature operation.

Applications

• Automotive infotainment systems requiring stable 5V power rails
• Vehicle telematics units with USB connectivity interfaces
• Digital cockpit displays and instrument clusters
• On-board diagnostic (OBD) ports and charging stations

Procurement Notes

Verify the specific suffix 'SACIL' matches the required tape-and-reel packaging configuration, as other variants may utilize tube packaging. Confirm that the 28-lead LFCSP footprint aligns with the target PCB layout dimensions. Ensure the selected component meets the specific AEC-Q100 grade requirements for the intended automotive zone. Cross-reference the exact part number with official Analog Devices documentation to confirm availability status, as supply constraints may affect lead times. Validate that the input voltage range supports the vehicle's operating conditions.

Selection Notes

Select this component when a single IC must handle both power conversion and USB interface logic for space-constrained automotive designs. The integrated emulator reduces external component count compared to discrete solutions. Consider the thermal performance of the exposed pad package for high-load scenarios. Verify that the 2.5A current rating suffices for the downstream load without excessive derating. Evaluate the switching frequency range to balance efficiency against EMI filtering requirements in sensitive automotive environments.

Part Context

This device belongs to the MAX16984 family of automotive power management ICs designed for complex electronic architectures. It consolidates multiple functions typically requiring separate chips into a single small form factor. The series targets modern vehicles where USB-C integration is standard for data and power delivery. It complements other Maxim Integrated PMICs by providing specialized interface handling alongside robust DC-DC conversion capabilities.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Direct replacements require matching the integrated USB emulator and protection features alongside the 2.5A buck converter specifications. Verify pin-to-pin compatibility if considering alternative packages within the same product family.
