4.1 EVM Jumpers

Tables 4-1, 4-2, 4-3, and 4-4 list the default jumper connections and functional descriptions for each device configuration. Each pinout configuration detailed in this section applies to all TPS3435-Q1, TPS3436-Q1, TPS35-Q1, and TPS36-Q1 device families. Please note that for pinouts A, B and C, Pin 7 refers to RESET for the TPS35-Q1 and TPS36-Q1 devices and WDO for the TPS3435-Q1 and TPS3436-Q1 devices.

Table 4-1 Pinout A Onboard Jumpers
PIN NUMBER / NAMEJUMPER CONNECTIONDEFAULT CONNECTIONDESCRIPTION

Jumper J4 configures the SET0 pin. Connect a shunt jumper to pins 1-2 of jumper J3 to input a logic high or to pins 2-3 to input a logic low. Please refer to the data sheet for SETx functionality.

Pin 6 / WDI

J5

Closed (pin 3, pin 4)

Jumper J5 configures the WDI pin. Connect a shunt jumper to pins 7-8 to input a WDI signal through TP3. A rising edge must be occur at this pin during the open window in order for RESET/WDO to not assert.

Pin 7 / RESET / WDO

J6

Closed (pin 1, pin 2)

Jumper J6 is used if there is an open-drain variant being evaluated. Connect a shunt jumper to pins 1-2 to activate pull-up resistor R2 and pull the RESET output high. Disconnect pins 1-2 if using a push-pull variant.

Pin 6 / WDI

J5

Closed (pin 3, pin 4)

Jumper J5 configures the WDI pin. Connect a shunt jumper to pins 7-8 to input a WDI signal through TP3. A rising edge must be occur at this pin during the open window in order for RESET/WDO to not assert.

Pin 7 / RESET / WDO
