TJA1020
Notes
1.
All parameters are guaranteed over the virtual junction temperature by design, but only 100% tested at 125
°
C
ambient temperature for dies on wafer level and above this for cased products 100% tested at 25
°
C ambient
temperature, unless otherwise specified.
For bare die, all parameters are only guaranteed if the backside of the bare die is connected to ground.
If V
BAT
is higher than 12 V, the battery current increases due to the internal LIN termination resistor. The minimum

value of this resistor is 20 k
. The maximum current increase is therefore:
