Product Details
UCS1001-1/2 USB Port Power Controller with Charger Emulation
The UCS1001 family of devices from Microchip are 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.
