2.2 Jumper Information

Table 2-2 Jumper Configurations
JumperFunction, Setting
J20, J21, J22

These jumpers are used to select the ILIM resistor for the device. J22/R13 selects 34.8kΩ and J21/R14 selects a solder down pad where any allowed 0805 resistor can be populated by the end user. J20 shorts the ILIM pin to ground.

J13, J16, J17

These jumpers are used to select the current sense resistor. J16/R11 selects 1kΩ, J13/R1 selects 500Ω, and J17/R12 enables the physical "SNS" potentiometer.
J24Enables and disables the onboard 5V LDO.
J9Latch (version A)/fault (version B) connection depending on chip version.

J6

Connects the DIAG_EN signal of the TPS482H85-Q1 to either the 5V signal or ground of the LDO.

J7

Connects the SEL signal of the TPS482H85-Q1 to either the 5V signal or ground of the LDO.

J4/J5

Connects the EN1/2 signal of the TPS482H85-Q1 to either the 5V signal or ground of the LDO.
J8Connects the LATCH signal of the TPS482H85-Q1 to either the 5V signal or ground of the LDO.
J14Bypasses the resistor and diode ground network and connects IC ground to system ground.

J12

Connects the VDD pin of the TPS482H85-Q1 to either the 5V signal or the J1 input supply of the LDO.

J2, J19, J23

Bypasses the input blocking diode (recommended for reverse polarity protection).

J15

Connects/disconnects the LDO from the TPS482H85-Q1. Disconnect when testing voltage transients greater than 60V.
