Connect the positive lead to the top (+) thermal and the negative lead to the bottom (–) terminal. 4.2 J2/J12 – VOUT Power Connections These are the high current output connections for loading the EVM. Connect the positive lead of the load to the top (+) terminal and the GND of the load to the bottom (–) terminal. 4.3 JP1/JP11 – VBIAS Power These jumpers connect VBIAS to the respective VIN voltage source. VBIAS must be maintained between 2.5 V–5.7 V for proper operation on the TPS22953 and TPS22954 devices. If testing conditions involve taking the VIN voltage below 2.5V, remove the shunt across JP1/JP11 and connect VBIAS voltage at TP2/TP12. 4.4 JP2/JP12 – EN Control These three pin jumpers connect the EN sense resistors either to VIN or to GND. This allow for quickly enabling/disabling the device after power is present. 4.5 TP1/TP11 – VIN Sense These connects provide and low current path to the input pins of the device for accurate voltage measurements. These sense connections 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. 4.6 TP4/TP14 – VOUT Sense These connects provide and low current path to the output pins of the device for accurate voltage measurements. These sense connections should be used when measuring the voltage drop from VIN to VOUT which is used to calculate the ON resistance. 4.7 TP7/TP17 – GND_Sense These test points provide a low current path to the GND pad of the device for accurate GND measurements. In cases where there is a large load current, it is recommended configure the power supply to use sense connections. Connect the negative sense lead to the GND_sense point to overcome voltage drop in cabling. 4.8 TP3/TP13 – EN These test points are used to monitor the EN pin voltage used for UVLO. These test points can also be used to drive the EN pin independently when JP2/JP12 is removed. 4.9 TP6/TP16 – SNS These test points are used to monitor the SNS pin voltage. 4.10 TP5/TP15 – PG These test points are used to monitor the PG pin voltage which is tied to VOUT through at 10kΩ resistor. 4 TPS22953/54 5.7-V, 5-A, 14-mΩ On-Resistance Load Switch Copyright © 2015, Texas Instruments Incorporated SLVUAG1 – March 2015 Submit Documentation Feedback EVM Connections www.ti.com 4.11 TP8/TP9/TP10/TP18/TP19/TP20 – GND These are the GND connection points to the EVM. 4.12 List of Connections The EVM Connections are summarized in Table 2.
