Description

The purpose of this board is to demonstrate the

features and capabilities of the ST204x and

ST205x USB power switches developed by

STMicroelectronics, using a Windows

host software application and one of several USB

low-speed microcontrollers from ST acting as a

peripheral device. The host software and the ST7

source code provides a clear picture of the power

switch capabilities. The USB communication

between host and the device is done through a

HID class based protocol developed specifically

for demonstration board applications. The

demonstration board incorporates a

microcontroller, programmable voltage regulator,

MOSFETS, switches and various resistive

networks. The on-board regulator can be

configured to supply various voltages by selecting

appropriate resistance from the resistive network

present at the adjust pin of the regulator. Different

voltages and loads can be selected from the PC

Input parameters:

– Load current: 100 mA, 500 mA, 1 A or 2 A.

– Input voltage: 4.4 V, 4.75 V, 5.0 V or 5.25 V

– Under-voltage protection

– Power switch: enable or disable option on

Output parameters:

– PC executable software (USBPS_GUI) for

– PC executable software (DFUGUI) for

– ST7 firmware (C source code) for the

Larger loads can be applied by properly

changing the load resistance (R37)

the GUI to control the voltage on the enable

pin of the power switch

software, as well as through switches present on

the board. LEDs are provided on the board to

indicate the various combinations of input voltage

and load applied to the power switch. The board

has an ICC connector to program the

microcontroller Flash memory. An external 12 V

charge pump is also provided on the board to

allow the user to perform in-application

programming (IAP) of the microcontroller

embedded Flash program memory. Any type of

real load (e.g. USB speakers) can be powered

from this board by plugging in the connector

present on the board
