DC-DC converter for automotive USB charging

13 November 2013 Power Electronics / Power Management

Recognising and then charging any portable device directly from a vehicle battery can be done over USB with a single IC, the MAX16984 automotive DC-DC converter with USB charge emulator from Maxim Integrated, which integrates all the functions of a traditional three-chip solution.

This single-chip solution combines a low-EMI 5 V automotive-grade DC-DC converter capable of driving up to 2,5 A with dynamic voltage adjustment, which is essential for charging contemporary portable devices over long automotive embedded cables; a USB Battery Charging Specification v1.2-compliant charge emulator, which conducts the necessary handshake between the portable device and upstream host instructing the portable device to increase its charge current; and integrated ESD diodes and USB over-voltage protection switches.

The MAX16984 is ideal for automotive radios and navigation modules, embedded telematics and connectivity modules, and USB-dedicated charging ports. It operates from a voltage up to 28 V and is protected from load dump transients up to 42 V. Integrated output adjustment eliminates cable voltage drop.
