3 Jumpers, Headers, Connectors, Test Points, and Switches
Table 3-1 , Table 3-2 , and Table 3-3 list all the jumpers, headers, connectors, test points, and switches on the
TLIN1431EVM and explain the functions of each of these components.
Table 3-1. Jumpers, Headers, and Connectors
Designator Function
J1 Connector for WDT/CLK, with adjacent VCC and GND pins for WDT triggering, or GND referencing for CLK
function.
J2 Connector for WKRQ/INH as described in Section 2.1.2 .
J3 Connector for EN/nINT, with adjacent pull-up to VCC and GND pins for interfacing the enable/interrupt pin.
J4 Generic output connector with multiple board signals connected. Pins 4-7, which are SPI communication pins in SPI
mode, are separated column-wise from the other signals on J4. The non-signal pins are connected to GND.
J5 Connector for PIN/nCS, which is used to configure the startup mode of the TLIN1431-Q1 as described in Section
2.1.1 and operates as chip-select in SPI mode.
J6 & J7 Channel expansion output as described in Section 2.4 .
J8 TXD and RXD connection as described in Section 2.9 .
J9 Terminal block connector for LIMP.
J10 Commander node selector, as described in Section 2.2 .
J11 Banana jack connector for the VBAT and GND supplies for the device.
J13 Connector for VBAT and VSUP.
J14 & J15 Configuration connectors for pull-up on WAKE pin, as described in Section 2.3 .
J16 LIN output with adjacent VBAT and GND pins.
J17 RXD pull-up selector, as described in Section 2.9 .
J18 Pull-down connector for LIMP. Connect a shunt to apply a 100 kΩ pull-down on the LIMP pin.
J21 GND connection rail.
