Hi-Speed USB analog switch

3 March 2010 Analogue, Mixed Signal, LSI

Maxim’s new MAX14550E is 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-compliant devices using a set resistor bias.

The device features a high-performance, Hi-Speed USB switch with low 4 pF on-capacitance and 4 Ω on-resistance. Operating over the -40°C to +85°C extended temperature range, the device is available in a 3 x 3 mm, 10-pin TDFN package.
