MAX14550E - Hi-Speed USB analog switch integrates USB host-charger identification circuit
Maxim has introduced the MAX14550E, a Hi-Speed USB analog switch with a USB host-charger identification circuit to automatically detect portable devices. This device allows a host to charge portable devices even when the host is in standby and cannot enumerate USB devices.
The MAX14550E supports the USB Battery Charging Specification Revision 1.0 with shorted D+/D- detection, as well as Apple(R)-compliant devices using a set resistor bias. Integrating this functionality within a single IC eliminates the need for multiple discrete components and minimizes software overhead. This low-cost solution is well suited for space-constrained notebooks and netbooks.The MAX14550E features a high-performance, Hi-Speed USB switch with low 4pF (typ) on-capacitance and low 4ohm (typ) on-resistance. Operating over the -40 degrees Celsius to +85 degrees Celsius extended temperature range, the device is available in a 3mm x 3mm, 10-pin TDFN package.
