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.
2. For bare die, all parameters are only guaranteed if the backside of the bare die is connected to ground.
3. If VBAT is higher than 12 V, the battery current increases due to the internal LIN termination resistor. The minimum
value of this resistor is 20 kΩ. The maximum current increase is therefore: IBAT(increase) = -V----B---A2---T-0----–-k---Ω1----2-----V--
4. tf(slope)(dom) = (---(--t--V----L--I--N-----=------4---0---%-----0-)---.-–5----5(---t--V---L---I-N------=-----9---5----%------)--) ; see Fig.6
5. tr(slope)(rec) = (---(--t--V----L--I--N-----=------6---0---%----0--)-.--5-–--5--(---t--V---L---I-N------=-----5---%------)---) ; see Fig.6
