Maxim launches MAX16984 automotive DC-DC converter

New Delhi, India, October 21, 2013: Maxim launches MAX16984 automotive DC-DC converter with USB charge emulator.

Previously, PDs like smartphones and tablets could not charge reliably from OEM stock USB ports in vehicles. Long embedded USB cables cause a voltage drop and reduce charging current, resulting in a PD to not properly charge. Low-cost portable USB car chargers introduce RF interference. Now, the MAX16984 brings intelligent USB charging into an automobile and solves these problems. This single-chip solution integrates all the functions of the traditional three-chip solution.

The MAX16984 combines a low EMI 5V automotive-grade DC-DC converter capable of driving up to 2.5A with dynamic voltage adjustment, which is essential for charging contemporary PDs over long automotive embedded cables; a USB Battery Charging Specification v1.2-compliant charge emulator, which conducts the necessary handshake between the PD and upstream host instructing the PD to increase its charge current; and integrated ESD diodes and USB over voltage protection switches, which provide robust industry-leading fault protection. The result is the fastest and most reliable PD charging with the smallest solution size. The MAX16984 is ideal for automotive radios and navigation modules, embedded telematics and connectivity modules, and USB-dedicated charging ports.

Ben Landen, Automotive Business Manager at Maxim Integrated, said, “The highly integrated, small MAX16984 allows industry-leading USB charging directly from a low-cost radio, hub, or dedicated charge port. The space and cost savings enable scalable designs into full vehicle fleets, across all sizes and classes, and help leverage consumer products into the automotive environment.”
MAX16984 automotive DC-DC converter available in 5mm x 5mm, 28-pin TQFN and QFND packages and it is AEC-Q100 qualified and specified over the -40°C to +125°C automotive temperature range.
