Smallest USB battery charger detectors offer universal charging potential
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.
An on-chip LDO provides a 5.3 V output which can be used to power a USB transceiver. In addition, ESD protection on the USB data pins is extended up to ±15 kV (Human Body Model) and ±8 kV IEC 61000-4-2 Contact Discharge. These features substantially reduce system complexity, component cost, and board space for today’s highly integrated consumer devices.
Availability
The MAX14578E/MAX14578AE are available in a 12-bump, 0.4 mm pitch, 1.3 mm x 1.68 mm 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.
