TJA1028 VCC OutputCurrent

[ban45]

Hi

The translation was incorrect.

①I would like to know the current that TJA1028 VCC can output.
Please tell me how many mA can be output when the input is 16V, the output is 5V, and the temperature is 85℃.
②The power supply data sheet contains a graph with power on the vertical axis and temperature on the horizontal axis.
Since it was not described in TJA1028, could you please tell me how to calculate the power and temperature and the graph?
③ Loss = (input voltage - output voltage) / output current?
I guess it fits.

best regard

[gw]70mA can be supported.

[gw] TJA1028 | LIN Transceiver with Integrated Voltage Regulator | NXP Semiconductors

You can download this power dissipation calculator for getting more info.
③ Loss = (input voltage - output voltage) / output current?

[gw]should be VIN*IIN -VOUT*IOUT
