SAN JOSE, Calif., Dec. 12, 2017 /PRNewswire/ -- Designers now
have a simpler, more cost-effective approach to enable fast and
safe charging of USB Type-C™ portable devices using 2-series Li-ion
battery packs. The highly efficient, highly integrated, 15W
MAX14748 USB Type-C charging and charger detection solution from
Maxim Integrated Products, Inc. (NASDAQ: MXIM) is the first such
solution on the market. The charger eliminates the patchwork of ICs
previously required to deliver the same capabilities, while
enabling designers to take advantage of only those USB Type-C
functions required for their particular design.

From wireless speakers to high-end cameras, virtual reality (VR)
headsets, and even motorized medical devices, there are a variety
of applications taking advantage of the simplicity of USB Type-C
connectors for charging and transferring multimedia data streams.
Two-series battery packs provide these applications with the power
they need to operate; however, these products also require ample
energy to recharge. Until now, developing USB Type-C products
powered by 2-series battery packs has required multiple discrete
components, increasing bill of materials (BOM) costs and
introducing additional points of failure within the circuit.
The MAX14748 streamlines the architecture by integrating a
charger, USB Type-C charger detection, 28V over-voltage protection,
and power path onto a single chip. The highly integrated solution,
which supports legacy USB BC1.2-compliant and other non-standard
chargers, enables USB Type-C charging at twice the power of Micro
USB solutions. A programmable Automatic Input Current Limiting
(AICL) feature safely draws the maximum current that the charging
adapter can supply, protecting valuable end equipment. With the
MAX14748, Maxim continues to extend its portfolio of power-related
products targeted for unique USB Type-C application needs. Existing
products in this category include the MAX77756 24V input, 500mA
buck regulator; the MAX17205 stand-alone ModelGauge™ m5 fuel gauge
with SHA-256 authentication; and the MAX20323 CC-pin overvoltage
protector.
Key Advantages
- Reduces power management footprint: Unlike typical
charging solutions, the MAX14748 minimizes the need for discrete
components by integrating a charger detector, boost/buck converter,
and Li-ion battery charger with a smart power selector on a single
chip
- Facilitates fast and safe charging: The MAX14748 charges
2-series lithium-ion batteries from legacy 5V USB adapters, while
its AICL feature prevents overcharging
- Provides additional protective features: The MAX14748
provides 28V integrated overvoltage protection, JEITA charge
protection, and ±15kV electrostatic discharge protection on USB
adapter pins
Commentary
- "The MAX14748 is the market's first solution that allows
designers to capitalize on the many benefits of USB Type-C
connectors and 2-series battery packs," said Sui Shieh, VP of the Industrial & Healthcare
Business Unit at Maxim Integrated. "Designers can now take
advantage of a simple, cost-effective way to extend fast and safe
lithium-ion battery charging to a wider range of battery-powered
products."
