Introduction

Pericom's PI5USB1458 and PI5USB1458A are the USB sleep & charge switch with Vbus switch control function
which provides multimode supports auto-detection and auto-switching between modes by detecting correctly plugged
in device.
The PI5USB1458 series evaluation board (EVB) is designed to demonstrate the benefits, performance and key
features of PI5USB1458 and PI5USB1458A. This user manual describes the usage of this EVB and it will be divided
into following sections:

Overview
Figure 1(a) & 1(b) are the block diagrams of Pericom PI5USB1458/PI5USB1458A EVB and Figures 2(a) & (b) are
the top and bottom view of EVB board. There is an USB plug connectors (J2) which is used to connect PC's USB
port and the USB receptacle connector (J1) is used to connect mobile devices. An external Vbus switch
PI5PD2068/PI5PD2069 is assembled on EVB which is controlled by the INT# / INT pin of
PI5USB1458/PI5USB1458A. The MODE setting in SW1 is used to select the normal USB operation and simulate
the Standby or Sleep mode (S3/ S4) of the PC. The LED D1 is used to show whether the circuit is over-current or
over-temperature. PI5USB1458/PI5USB1458A operation required +5V which was supplied by the PC through the
USB connector (J2) or external power supply +5V through JP2 & JP3.
