STEVAL-PCN001V1 USB power switch demonstration board is a board used to demonstrate the ST204x and ST205x USB power switches. The board has load current, input voltage, under-voltage protection, power switch and other features.
The STEVAL-PCNO01V1 is a demonstration board designed to showcase the features of STMicroelectronics' ST204x and ST205x USB power switch families. It utilizes Windows-based host software and low-speed microcontrollers from ST as peripheral devices, communicating via a specific HID class protocol.
The board incorporates an on-board regulator configurable for various voltages, MOSFETs, switches, and resistive networks to support load currents of 100 mA up to 2 A. It includes PC executable software (USBPS_GU) for control and firmware upgrading, as well as source code for the ST7 microcontroller.
| Load current | 100 mA, 500 mA, 1 A or 2A |
|---|---|
| Input voltage | 4.4 V, 4.75 V, 5.0 V of 5.25 V |
| Protection feature | Under-voltage protection |
The demonstration board uses one of several USB low-speed microcontrollers from ST acting as a peripheral device.
The board has an ICC connector to program the microcontroller Flash memory.
