    • Two power supplies for VBAT and VDDIO – 3.3 V at 100 mA recommended for each Items Recommended for Operation The following items are recommended for use with the TSU6721EVM: • MSP430™ LaunchPad™ – Recommended rev 1.5 – MSP430G2553 installed •...
  • Page 3: Introduction

    Introduction www.ti.com Introduction The TSU6721EVM can be used as a standalone board or paired with the MSP-EXP430G2 LaunchPad to facilitate power and I C communication. When paired with the LaunchPad, The TSU6721EVM graphical user interface (GUI) can be used to read from or write to internal registers of the TSU6721 micro-USB switch, allowing the user to observe or control the switching of the device through I Table 1.

    According to page 23 of the TSU6721 datasheet, the TSU6721 is now in manual switching mode. Attach VBUS or a valid ID resistance to the TSU6721EVM. The attachment will not determine the switch status, but it will ensure that the TSU6721 does not enter sleep mode, allowing manual switching to work properly.
