What are the key features of MAX16984SAGI/VY+T?
- Automotive AEC-Q100 qualified current-mode PWM step-down converter operating from 4.5 V to 28 V input
- Integrated USB host charger adapter emulator and USB port protection in a single 28-pin LFCSP (5x5x0.85 mm) package
- Current-mode pulse-width modulation control for superior line and load transient response with excellent stability
What is MAX16984SAGI/VY+T used for?
The MAX16984SAGI/VY+T is designed for automotive infotainment, telematics, and body-control modules that require a regulated step-down power rail from a 12 V car battery. It is also well-suited for in-vehicle USB charging stations, where its integrated adapter emulator automatically negotiates charging profiles for connected devices. Industrial power-supply designs requiring wide input voltage tolerance up to 28 V with robust overcurrent protection also benefit from this device.

Frequently Asked Questions
What input voltage range does the MAX16984SAGI/VY+T support, and is it suitable for 12 V automotive systems?
The MAX16984SAGI/VY+T accepts input voltages from 4.5 V to 28 V, making it fully compatible with standard 12 V automotive battery rails that can swing up to 24 V during load-dump transients. It is AEC-Q100 qualified, ensuring reliable operation across automotive temperature and stress conditions.
How does the integrated USB host charger adapter emulator in MAX16984SAGI/VY+T simplify automotive USB charging designs?
The built-in USB host charger adapter emulator automatically applies the correct resistive signatures on the D+ and D- lines so connected devices can draw up to 1.5 A without a separate dedicated charging controller IC. This integration reduces BOM count, saves PCB area in the 5x5 mm footprint, and guarantees compliance with USB Battery Charging Specification Rev 1.2 requirements.
Which control topology does MAX16984SAGI/VY+T use, and why does it matter for transient performance?
MAX16984SAGI/VY+T uses current-mode pulse-width modulation (PWM) control, which provides an inherent inner current-feedback loop. This topology achieves cycle-by-cycle overcurrent limiting and faster load-transient response compared to voltage-mode controllers, typically settling within a few microseconds for step-load changes on automotive output rails.
What package does MAX16984SAGI/VY+T use, and how does it aid thermal management in automotive designs?
The device comes in a 28-pin LFCSP (5 mm x 5 mm x 0.85 mm) with an exposed paddle on the bottom. The exposed thermal pad provides a direct thermal path to the PCB copper, enabling effective heat spreading at high output currents without the need for an external heatsink, which is critical in space-constrained automotive module designs.
