Product Details

UCS1003-1/2/3 USB Port Power Contoller with Charger Emulation

The UCS1003 family of devices from Microchip is a range USB Port Power Switches that offer precise power control. These devices offer the option of split supply support for VS and VDD for low power in system standby states.

In battery operated applications the device can detect attachments from a Sleep or an Off state. After the Attach Detection is flagged, the system can decide to wake-up and/or provide charging. Included is the capability to automatically charge a wide range of portable/peripheral devices; nine emulation profiles maximise the compatibility coverage offered.
