3.2 EVM Jumpers

Table 3-2 lists the jumpers on the TPS37AQ1EVM. As ordered, the EVM will have seven jumpers installed.

Table 3-2 Jumpers
Jumper Default Connection Description
J1 Open SENSE1 voltage divider jumper. Connects VDD to a halving voltage divider which feeds into SENSE1 if populated. (R1 = R2 = 49.9kΩ)
J2 Open SENSE2 voltage divider jumper. Connects VDD to a halving voltage divider which feeds into SENSE2 if populated. (R1 = R2 = 49.9kΩ)
J3 Closed Pullup jumper to connect RESET1 via a 10.0kΩ resistor to VDD (disconnect for push-pull configuration devices or to pullup to different voltage)
J4 Closed Pullup jumper to connect RESET2 via a 10.0kΩ resistor to VDD (disconnect for push-pull configuration devices or to pullup to different voltage)
J5 Closed on top 2 pins Selectable jumper to pick between halving voltage divider connection and direct VDD connection to SENSE1 (top 2 pins = voltage divider; bottom 2 pins: SENSE1 = VDD)
J6 Closed on top 2 pins Selectable jumper to pick between halving voltage divider connection and direct VDD connection to SENSE2 (top 2 pins = voltage divider; bottom 2 pins: SENSE2 = VDD)
J7 Closed on position 1 Selectable jumper to pick between 4 options for terminating CTS1 (pin 7). Position 1 = 1uF, Position 2 = 0.01uF, Position 3 = 0.033uF, Position 4 = non stuffed to customize
J8 Open Selectable jumper to pick between 3 options for terminating CTR1/MR (pin 6). Position 1 = non stuffed to customize, Position 2 = 10nF, Position 3 = GND (force Manual Reset)
J9 Open Selectable jumper to pick between 3 options for terminating CTR2/MR (pin 9). Position 1 = non stuffed to customize, Position 2 = 10nF, Position 3 = GND (force Manual Reset)
J10 Closed on position 1 Selectable jumper to pick between 4 options for terminating CTS2 (pin 8). Position 1 = 1uF, Position 2 = 0.01uF, Position 3 = 0.033uF, Position 4 = non stuffed to customize
J11 Closed Connects both SENSE1 and SENSE2 together to allow for single channel undervoltage and overvoltage monitoring. Disconnect to operate inputs/outputs separately.
