MAX16984

Automotive High-Current Step-Down Converter with

USB Protection/Host Charger Adapter Emulator

General Description

Features

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 Specification

BC1.2 battery charging specification and Chinese Tele-

communication Industry Standard YD/T 1591-2009. They

also include circuitry for iPod®/iPhone® 1.0A and iPad®

2.1A dedicated charging modes. The HVD+ and HVD-

ESD protection features include protection to 15ꢀV

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

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

S High-Efficiency DC-DC Controller

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

 5V, 2.5A Output Current Capability

 User-Adjustable USB Current Limit

 Fixed-Frequency 220kHz to 2.2MHz Operation

 Forced-PWM Option at No Load

 Spread Spectrum for EMI Reduction

 SYNC Input for Frequency Parking

 Low Q Current Skip Mode and Low Q Shutdown

 Reduced Inrush Current by Soft-Start

S Integrated Output Adjustment for Cable Voltage

Drop

 User-Adjustable Voltage Gain

 Up to 3 Meter Cable/Up to 600mω

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-programmable frequency selection from 220ꢀHz

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 Schottꢀy 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 sꢀip 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.

S USB D+/D- Protection and Host Charger Emulator

 4I 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

 Chinese Telecommunication Industry Standard

YD/T 1591-2009

 High-Speed Pass-Through Mode

 Short to Battery and Short to V

 Compatible with USB On-the-Go Specification

S Split Supplies SUP and SUPSW Minimize Power

Consumption

S Fault Indication Active-Low Open-Drain Output

S Automotive Grade ESD Protection (HVD )

 25kV Air/ 8kV Contact ISO 10605

The MAX16984 also includes a USB load current-sense

amplifier and configurable feedbacꢀ adjustment circuit

designed to provide automatic USB voltage adjustment

to compensate for voltage drops in captive cables asso-

ciated with automotive applications. The MAX16984 lim-

its the USB load current using both a fixed internal peaꢀ

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

configurable external USB load current-sense amplifier

threshold.

 15kV Air/ 8kV Contact IEC 61000-4-2

 15kV Air/ 8kV Contact (330I, 330pF)

S Overtemperature and Short-Circuit Protection
