SLLU131B – July 2010 – Revised February 2011
Power Switch
The DEMO Baord uses a TI TPS2561 power switch. This switch serves two purposes. It limits the amount
of in-rush current on VBUS and it allows power to the SATA connector to be switched via the TUSB9260.
The switch is controlled via GPIO10 from the TUSB9260 and power faults can be monitored by GPIO11.
By default the DEMO Board is configured to always apply power to the SATA connector and power faults
are not monitored.
