Quickly and Reliably Charge Any Portable Device over USB in a Car with a Single IC
Maxim Integrated's automotive DC-DC converter with cable drop compensation integrates a smart USB charge emulator to enable fast and reliable charging for portable devices (PDs).
SAN JOSE, Calif., Oct. 16, 2013 /PRNewswire/ -- Recognizing and then charging any portable device (PD) directly from a vehicle battery can now be done over USB with a single IC, the MAX16984 automotive DC-DC converter with USB charge emulator from Maxim Integrated Products, Inc. (NASDAQ: MXIM).

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.
Key Advantages
-- High integration: the MAX16984 combines the functions of the standard
three-chip solution: a 5V automotive-grade DC-DC converter capable of
driving up to 2.5A, a USB BC1.2 charge adapter emulator, and USB
protection switches for automotive USB host applications.
-- Higher performance: the MAX16984 operates from a voltage up to 28V and
is protected from load dump transients up to 42V; integrated output
adjustment eliminates cable voltage drop.
-- Reduced power: the MAX16984's automotive USB function communicates with
a connected PD and switches to low-power mode when not in use, thus
reducing power consumption.
-- Safe charging: the MAX16984 is the only USB protection IC with
integrated ESD diodes, which prevent damage to the vehicle's radio or
peripheral components.
Industry Commentary
-- "The highly integrated, small MAX16984 allows industry-leading USB
charging directly from a low-cost radio, hub, or dedicated charge port,"
said Ben Landen, Automotive Business Manager at Maxim Integrated. "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."
-- "Smartphones and tablets are today's rear-seat entertainment," said
Richard Robinson, Director of Automotive Analysis at Strategy Analytics.
"The increasing requirement for automotive infotainment will boost the
supporting semiconductor market to over $7.0 billion in 2018."
Availability and Pricing
-- Available in 5mm x 5mm, 28-pin TQFN and QFND packages.
-- The MAX16984 is AEC-Q100 qualified and specified over the -40-degree
Celsius to +125-degree Celsius automotive temperature range.
-- Contact factory for pricing.
