Page 8: Port Power Switch Transistors
The integrated analog overcurrent detection circuit of the ISP1521 senses the voltage drop across the power switch. When the port draws too much current, the voltage drop across the power switch exceeds the trip voltage threshold. The overcurrent circuit detects this and automatically switches off the power switch. - Page 9 UM10011_4 Philips Semiconductors ISP1521 Hi-Speed USB Hub Demo Board Figure 5-1: Windows Reporting of the Bus-Powered Mode © Koninklijke Philips Electronics N.V. 2004.
