3.2 EVM Jumpers

Table 3-2 lists the jumpers on the TPS3760EVM. As ordered, the EVM will have twelve jumpers installed.

Table 3-2 Jumpers
JumperDefault ConnectionDescription
J1Closed on top 2 pinsSelectable jumper to pick between halving voltage divider connection and direct VDD connection to SENSE2 (bottom 2 pins = voltage divider; top 2 pins: SENSE2 = VDD)
J2OpenSENSE2 voltage divider jumper. Connects VDD to a halving voltage divider which feeds into SENSE2 if populated. (R1 = R2 = 49.9kΩ)
J3Closed on top 2 pinsSelectable jumper to pick between halving voltage divider connection and direct VDD connection to SENSE1 (bottom 2 pins = voltage divider; top 2 pins: SENSE1 = VDD)
J4OpenSENSE1 voltage divider jumper. Connects VDD to a halving voltage divider which feeds into SENSE1 if populated. (R1 = R2 = 49.9kΩ)
J5Closed on left to middle pinsPullup jumper to connect RESET1 via a 10.0kΩ resistor to VDD (disconnect for push-pull configuration devices or connect from middle to right to pullup to different voltages)
J6Closed on left to middle pinsPullup jumper to connect RESET2 via a 10.0kΩ resistor to VDD (disconnect for push-pull configuration devices or connect from middle to right to pullup to different voltages)
J7ClosedJumper to add a 100nF capacitor to the SENSE2 input.
J8ClosedJumper to add a 100nF capacitor to the SENSE1 input.
J9OpenSelectable jumper to pick between 6 options for terminating CTS1. Capacitor sizes are marked on board and are the following, from bottom to top: DNI (solder custom capacitor here if desired), 1nF, 10nF, 100nF, 1uF, 10uF.
J10OpenSelectable jumper to pick between 6 options for terminating CTS2. Capacitor sizes are marked on board and are the following, from top to bottom: DNI (solder custom capacitor here if desired), 1nF, 10nF, 100nF, 1uF, 10uF.
J11OpenSelectable jumper to pick between 7 options for terminating CTR1/MR pin. Capacitor sizes are marked on board and are the following, from bottom to top: Open (Connect to GND to test MR functionality, DNI (solder custom capacitor here if desired), 1nF, 10nF, 100nF, 1uF, 10uF.
J12OpenSelectable jumper to pick between 7 options for terminating CTR2/MR pin. Capacitor sizes are marked on board and are the following, from top to bottom: Open (Connect to GND to test MR functionality, DNI (solder custom capacitor here if desired), 1nF, 10nF, 100nF, 1uF, 10uF.
