UCS1003-1-BP UCS1003-1 by Microchip Technology
USB Port Power Controller with Charger Emulation
| Status: | Unknown |
|---|---|
| Series: | - |
| RoHS: | Unknown |
The UCS1003 provides a USB port power switch for precise control of up to 2.7 amperes continuous current with over-current limit (OCL), dynamic thermal management, latch or auto-recovery (low test current) fault handling, selectable active low or high enable, under- and over-voltage lockout, back-drive protection, back-voltage protection and charge active signal*.
Split supply support for VS and VDD is an option for low power in system standby states. This gives battery operated applications, like notebook PCs, the ability to detect attachments from a sleep or off state. After the Attach Detect is flagged, the system can decide to wake up and/or provide charging.
In addition to power switching and current limiting modes, the UCS1003 will automatically charge a wide variety of portable devices, including USB-IF BC1.2, YD/T-1591 (2009), most Apple®, Samsung, and RIM®, and many others. Nine preloaded charger emulation profiles maximize compatibility coverage of peripheral devices. As well, a customizable charger emulation profile** is available to accommodate unique existing and future portable device handshaking/signature requirements.
The UCS1003 also provides current monitoring** to allow intelligent management of system power and charge rationing for controlled delivery of current regardless of the host power state. This is especially important for battery operated applications that want to provide power in a standby and/or off state but do not want to drain the battery excessively.
The UCS1003 is available in a 20-pin QFN 4 mm x 4 mm package.
