2. Series Resistor at Pin BAT of the TJA1053 / TJA1054

The following considerations are recommended for the determination of the series resistor (R
BAT
)
being attached to the supply input BAT (pin 14) of the TJA1053 / TJA1054 transceiver products.
The minimum recommended series resistance is about 1 kOhms for protection purpose against
automotive transients. On the other hand the series resistance implies voltage drop on the battery
supply and therefore lowers the minimum operating voltage. The voltage drop across the R
BAT
series
resistance can be calculated with the following consideration:
