Instructions for Using TJA1042

1. Power Supply Connection:

   • Connect the V_CC pin to a stable power supply within the range of 3.0V to 5.5V.
   • Ensure that the ground (GND) pin is connected to the system ground.

2. Signal Connections:

   • Connect the CAN_H and CAN_L pins to the CAN bus lines.
   • The differential input voltage (V_DIFF) should be within 卤12V to avoid damage.
   • The common-mode input voltage (V_CM) should be within -2V to 14V.

3. Standby Mode:

   • To enter standby mode, set the STB pin to a high state.
   • In standby mode, the quiescent current (I_CCQ) will be reduced to approximately 20-40 渭A.

4. Active Mode:

   • To enter active mode, set the STB pin to a low state.
   • In active mode, the current consumption (I_CCA) will be approximately 8-15 mA.

5. Output Current Limit:

   • The output current limit (I_OLIM) is set to protect the device from overcurrent conditions. It is typically between 1.0A and 2.0A.
   • If the output current exceeds this limit, the device will enter a short-circuit protection mode.

6. Short-Circuit Protection:

   • The device has built-in short-circuit protection that limits the output current and protects the device from damage.
   • The maximum duration for short-circuit protection is 60 ms.

7. Temperature Considerations:

   • The operating temperature range (T_OP) is from -40掳C to 125掳C.
   • The storage temperature range (T_STG) is from -40掳C to 150掳C.
   • Ensure that the device is not operated outside these temperature ranges to prevent damage.

8. ESD Protection:

   • The device includes ESD protection, but it is recommended to handle the device with care to avoid static discharge.

9. Layout Considerations:

   • Use short and direct traces for the CAN_H and CAN_L connections to minimize signal degradation.
   • Place decoupling capacitors close to the V_CC and GND pins to ensure stable power supply.

By following these instructions, you can ensure reliable and efficient operation of the TJA1042 CAN transceiver.
