3.4 Jumper Description

Jumpers J1, J2, J13, J14

can be powered by the input power supply pin A, Jump J2-2, 3 and J14-2, 3. When it is powered by

the load, pin C, jump J2-1, 2 and J14-1, 2. If A and C are less than 3 V, connect the 5 V to V

, jumper

J1-1 to J2 -2 and J13-1 to J14-2.

J3, J15

Jumpers J3 and J15 connect a pot to the RSET pin when testing the TPS2411. These jumpers are

normally left open when testing the TPS2410.

J4, J17

Jumpers J4 and J17 are open to enable the UV and OV inputs to the TPS2410.

Jumper J6 is on to connect the STAT pins together on both TPS2410 channels. When the STAT pin is

low, the turn off of the channel powering the load is de-sensitized.

Jumper J8 is the gate voltage for the Glitch FET. Jump J8-2, 3 when the PS1 voltage is greater than 5 V.

Jump J8-1, 2 to use the 5-V supply when PS1 is less than 5 V.

J16

Jumper J16-2, 3 connects pin C to the load for single or parallel FETs. Connect J16-1, 2 to protect the pin

A and C inputs when output FETs are configured back-to-back.

3.5 Procedure – Jumper Set-Up

An initial jumper setup is recommended in Table 2. The module has flexibility to operate in other modes.

Change jumpers to operate in other configurations as required after getting started. After the initial setup,

reference the schematic and set jumpers as required for testing. Other J reference designators on the

schematic are simple connectors.
