2.8.2 Other Control Headers

Other headers on the EVM can be used to easily control specific functions of the TCAN24xx-Q1 or to interface with the outputs.

Table 2-3 Control Headers
Header Function

J6

Enables the 5V LDO (U3). Use a shunt to pull the EN pin to either VSUP or VCC2 via a 10kΩ resistor.

J7

VCAN supply selector. Use a shunt to connect the VCAN rail to either VCC2 or the 5V output from the LDO (U3).

J11

Apply a shunt on this header to synchronize HSS1 and HSS2.

J16/J20

Apply a shunt on these headers to connect a subcircuit that allows for simulated bus loading.

J17/J21

Apply a shunt on these headers to connect a 120Ω standard termination resistor to the bus (R41).

J18/J22

Apply a shunt on these headers to connect split termination to the bus using two 60Ω resistors (R39/R42) and a 4.7nF capacitor (C26).

J25

Apply a shunt to connect the VLED and 5V rails, which allows the onboard LEDs to be powered using the 5V LDO (U3).

SJ5

Close this solder jumper to allow VBAT to be connected to pin 5 of the DB9 CAN connector (J15).
