Maxim has introduced the MAX14566E, a USB charger identification solution that supports the charging of portable devices from notebook computers, even when the computer is in sleep or hibernate mode.

The switch supports the USB battery charging specification, revision 1.1, as well as the CCSA YD/T 1591-2006 standard for the Chinese market.

The switch automatically identifies the type of portable device connected using its charger identification circuit. Requiring no external software, this circuit allows a host USB port to support USB battery charging specification, revision 1.1-compliant devices with shorted D+/D- detection, as well as Apple devices by using a resistor bias.

The device also features a high-performance, Hi-Speed USB switch with low 4 pF on-capacitance and low 4 Ω on-resistance.

Operating over the -40 to +85°C temperature range, the switch is available in a 2 x 2 mm, 8-pin TDFN package.
