The device contains an N-channel MOSFET that can operate over an input voltage range of 0.8 V to 5.7 V and can support a maximum continuous current of up to 6 A. The switch is controlled by an active high on and off input (ON), which is capable of interfacing directly with low-voltage GPIO control signals. The rise time of the device is internally controlled in order to avoid inrush current and can be adjusted using an external ceramic capacitor on the CT pin. The TPS22965N device is available in a small, space-saving 2-mm × 2-mm 8-pin SON package with integrated thermal pad allowing for high-power dissipation.

Connect the positive lead of the power supply to either terminal. 4.2 J2 – VOUT Power Connection This is the high current output connection for loading the EVM. Connect the positive lead of the load to either terminal. 4.3 JP1 – VBIAS Power This jumper connects VBIAS to the VIN voltage source. VBIAS must be maintained between 2.5 V – 5.7 V for proper operation on the TPS22965N device. If testing conditions involve taking the VIN voltage below 2.5 V, remove the shunt across JP1 and connect VBIAS voltage at TP4. 4.4 JP2 – ON Control This three pin jumper connects the ON pin to either VIN or GND, which allows for quickly enabling/disabling the device after power is present. 4.5 TP2 – ON This test point is used to monitor the EN pin voltage. This test point can also be used to drive the ON pin independently when JP2 is removed. 4.6 TP3 – VIN Sense This test point provides a low current path to the input pins of the device for accurate voltage measurements. This sense connection should be used when measuring the voltage drop from VIN to VOUT which is used to calculate the ON-resistance. In cases where there is a large load current, it is recommended configure the power supply to use sense connections. Connect the positive sense lead to the VIN sense point to overcome voltage drop in cabling. 4.7 TP5 – VOUT Sense This test point provides a low current path to the output pins of the device for accurate voltage measurements. This sense connection should be used when measuring the voltage drop from VIN to VOUT which is used to calculate the ON resistance. 4.8 TP7/TP8/TP9/TP10 – GND These are the GND connection points to the EVM. 4 TPS22965NEVM User's Guide SLVUAG9 – May 2015 Submit Documentation Feedback Copyright © 2015, Texas Instruments Incorporated EVM Connections www.ti.com 4.9 List of Test Points Table 1.

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.
