Battery Charger Detectors comply with USB specification.
Press Release Summary:
In addition to proprietary charger adapters from Apple and Sony, Models MAX14578E/MAX14578AE detect USB standard downstream ports, USB charging downstream ports, or dedicated charger ports. When charging port is detected, devices will control external lithium-ion battery charger controller to optimize charge time and efficiency. On-chip LDO provides 5.3 V output, which can be used to power USB transceiver. Operating from -40 to +85°C, ICs offer ±15 kV HBM ESD protection on USB data pins.

Maxim's Smallest USB Battery Charger Detectors Provide a Virtually Universal Charging Experience
Maxim Integrated Products' complete port-detection devices are compliant with USB Battery Charging Specification and work with virtually any proprietary power adapters.
Sunnyvale, CA- - Maxim Integrated Products Inc. (NASDAQ: MXIM) today announced the MAX14578E/MAX14578AE, the industry's smallest USB battery charger detectors that are compliant with the USB Battery Charging Specification. These devices detect USB standard downstream ports (SDPs), USB charging downstream ports (CDPs), or dedicated charger ports (DCPs), in addition to proprietary charger adapters from Apple and Sony. When a charging port is detected, the MAX14578E/MAX14578AE will control an external lithium-ion (Li+) battery charger controller to optimize charge time and charging efficiency.
By supporting a broad range of USB chargers, the MAX14578E/MAX14578AE offer consumers a "virtually universal" charging experience. Manufacturers also can now ship equipment without including power adapters, so they simplify their manufacturing supply chain while improving their green credentials.
"The MAX14578E/MAX14578AE allow the consumer to charge from a wide variety of sources," said Andrew Baker, Director, Business Management at Maxim Integrated Products. "With this level of flexibility, consumers may never have to own a device with a dedicated charger again."
An on-chip LDO provides a 5.3V output which can be used to power a USB transceiver. In addition, ESD protection on the USB data pins is extended up to ±15kV (Human Body Model) and ±8kV IEC 61000-4-2 Contact Discharge. These features substantially reduce system complexity, component cost, and board space for today's highly integrated consumer devices.
The MAX14578E/MAX14578AE are available in a 12-bump, 0.4mm pitch, 1.3mm x 1.68mm WLP package for space-critical applications, and in a 16-pin TQFN package for ease of manufacturing. They operate over the -40°C to +85°C extended temperature range. An evaluation kit is available: MAX14578EVKIT
