Table 5-2 shows the relevant configuration jumpers of the TPS281C30EVM as well as the associated values. Please refer to the TPS281C30 data sheet for detailed information on each pin's functionality.
Please note that a white mark on the jumper silkscreen is reflecting the position 1 of the jumper.
| Jumper | Function, Settings |
|---|---|
| J5 | Connect 1 and 2 to disable on-board LDO; connect 2 and 3 to enable on-board LDO. |
| J6 | Connect 1 and 2 to pull ENABLE high; connect 2 and 3 to pull ENABLE low. |
| J7 | Connect 1 and 2 to pull DIAG_EN high; connect 2 and 3 to pull DIAG_EN low. |
| J8 | Connect 1 and 2 to pull OL_ON high; connect 2 and 3 to pull OL_ON low. |
| J9 | Connect to keep output at 0 V during inductive turn-off; disconnect for TVS clamp to clamp the output (default to –10 V) during inductive turn-off. |
| J10 | Connect the 24.9 kΩ resistor to ILIM pin. Resistor will be paralleled if J11 is also connected. |
| J11 | Connect the 16.9 kΩ resistor to ILIM pin. Resistor will be paralleled if J11 is also connected. |
| J12 | Connect 1 and 2 to use LDO for FAULT pullup; connect 2 and 3 to use BoosterPack plug-in module 3.3 V for FAULT pullup. |
| J13 | Connect to bypass GND network. Disconnect to use GND network. |
| J14 | Connect to power the BoosterPack plug-in module with LDO. |
