Pressing S1 pulls PWRBTNIN to GND. The power button can be used for many features such as turn on after a RESET or causing a RESET if configured correct via I2C. See the datasheet for more options and uses of the power button. 4.2.2 S2 – Multi-Switch Shutdown, NVDC, and 3.3-V Load Switch This switch has 4 dip switches in it. Switch 1 is unused. Switch 2 is internal 3.3-V load switch enable. Set away from the ON position to enable the internal 3.3-V load switch. Switch 3 is NVDC selector. Set towards the ON position to put the device into NVDC mode. Switch 4 is Shutdown mode. Set towards the ON position to put the device into SHUTDOWN mode. 4.3 Enables There are places for jumpers to enable the VRs directly on the board. However, the TPS650830EVM has other jumpers that set the Sleep States for the device. The sleep states indirectly enable the VRs. VR2 and VR3 are already on before any enable switch asserting high. They are enabled by DPWROK and LDO3, respectively, with LDO3 enabled when VIN > UVLO. 10 TPS650830EVM-095 SLVUAD6 – December 2014 Submit Documentation Feedback Copyright © 2014, Texas Instruments Incorporated Setup www.ti.com 4.3.1 J4 - SLP_SUS# SLP_SUS# is active low and when set low will put the device into sleep state SUSPEND. When SLP_SUS# asserts high, VR5 and VR1 turn on as well as the device enabling a load switch. 4.3.2 J4 - SLP_S4# SLP_S4# is active low and when set low will put the device into sleep state 4. When SLP_4# asserts high, VR4 turns on as well as the device enabling a load switch. 4.3.3 J4 - SLP_S3# SLP_S3# is active low and when set low will put the device into sleep state 3. When SLP_3# asserts high, the device enables a load switch. 4.3.4 J4 - SLP_S0# SLP_S0# is active low and when set low will put the device into sleep state 0.

Hardware Board Connection Before connecting the EVM, always remember to preset the power supply to correct voltages. Never "hot plug" or connect the power supply to the EVM with the power supply on. This can result in 2x input voltage overshoot that can damage the devices on the EVM. Connect the EVM as shown in Figure 8. Before turning on the power supply, set the SLP_Sx# jumpers to LOW as they must be sequenced in the proper order for correct power up. The order for sequence is SLP_SUS# → SLP_S4# → SLP_S3# → SLP_S0#. Once the power supply is on and providing a valid VIN voltage, the SLP_Sx# signal can be set to HIGH in the listed sequence. After this, the EVM will have all power rails ON and regulating to their set voltage. ALL_SYS_PWRGD, TP71, should be HIGH signaling a valid power up of the system. 5.2 Software Setup To install the GUI, first download the GUI from the Tools & Software folder at http://www.ti.com/product/TPS650830/toolssoftware.

Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
