MAX16984

Automotive High-Current Step-Down Converter with

USB Protection/Host Charger Adapter Emulator

General Description

Beneﬁts and Features

● Integrated DC-DC and USB Host Charge Emulator

Enables 1-Chip Solution Directly from Car Battery to

Portable Device

The MAX16984 combines a 5V automotive-grade step-

down converter capable of driving up to 2.5A, a USB host

charger adapter emulator, and USB protection switches

for automotive USB host applications. The USB protection

switches provide high-ESD, short-circuit protection and

feature integrated host-charger port-detection circuitry

adhering to the USB 2.0 Battery Charging Specifica-

tion BC1.2 battery charging specification and Chinese

Telecommunication Industry Standard YD/T 1591-2009.

• 4.5V to 28V (42V Load Dump) Operating Voltage

• 5V, 2.5A Output Current Capability

• Low Q Current Skip Mode and Shutdown Modes

• Soft-Start Reduces Inrush Current

● Low-Noise Features Prevent Interferene with AM

Band and Portable Devices

They also include circuitry for iPod /iPhone 1.0A and

• Fixed-Frequency 220kHz to 2.2MHz Operation

• Forced-PWM Option at No Load

• Spread Spectrum for EMI Reduction

• SYNC Input for Frequency Parking

iPad 2.1A dedicated charging modes. The HVD+ and

HVD- ESD protection features include protection to ±15kV

Air/±8kV Contact on the HVD+ and HVD- outputs to the

IEC 61000-4-2 model and 330Ω, 330pF ESD model.

● Optimal USB Power and Communication for

Portable Devices

The high-efficiency step-down DC-DC converter

operates from a voltage up to 28V and is protected from

load dump transients up to 42V. The device is optimized

for high-frequency operation and includes resistor-pro-

grammable frequency selection from 220kHz to 2.2MHz

to allow optimization of efficiency, noise, and board space

based on application requirements. The converter has

an internal high-side n-channel switch and uses a low

forward-drop freewheeling Schottky diode for rectification.

There is a small lowside n-channel switch to maintain

fixed frequency under light loads. For lower quiescent

current operation requirements, the low side n-channel

switch can be disabled to allow skip mode operation

under light loads. The converter can deliver up to 2.1A

of continuous current at 105°C. The MAX16984S has

an integrated spread-spectrum oscillator to improve EMI

performance.

• User-Adjustable Voltage Gain Adjusts Output Be-

tween 5V and 6.15V for Cable Compensation

• ±3% Accuracy User-Adjustable USB Current Limit

• 4Ω USB 2.0 480Mbps/12Mbps Data Switches

• Integrated iPod/iPhone/iPad Charge-Detection

Termination Resistors

• Supports USB BC1.2 Charging Downstream Port

(CDP) and Dedicated Charging Port (DCP) Modes

• Supports Chinese Telecommunication Industry

Standard YD/T 1591-2009

• High-Speed Pass-Through Mode

● Robust Design Keeps Vehicle System and

Portable Devices Safe in Automotive Environment

• Short-to-Battery Protection on DC-DC Converter

•

Short-to-Battery Protection on USB Pins

• ±25kV Air/±8kV Contact ISO 10605

• ±15kV Air/±8kV Contact IEC 61000-4-2

• ±15kV Air/±8kV Contact (330I, 330pF)

• Fault-Indication Active-Low, Open-Drain Output

• Reduced Inrush Current with Soft-Start

• Overtemperature Protection

• -40NC to +125NC Operating Temperature Range

• 28-Pin, 5mm x 5mm, TQFN and Side-Wettable

QFND Packages

The MAX16984 also includes a USB load current-sense

amplifier and configurable feedback adjustment circuit

designed to provide automatic USB voltage adjustment to

compensate for voltage drops in captive cables associat-

ed with automotive applications. The MAX16984 limits the

USB load current using both a fixed internal peak current

threshold of the DC-DC converter and a user-configurable

external USB load current-sense amplifier threshold.

Applications

● Automotive Radio and Navigation

● USB Port for Host and Hub Applications

● Automotive Connectivity
