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.
