Self-supplied high-speed CAN transceiver with Standby mode
8. Thermal characteristics
[1] According to JEDEC JESD51-2, JESD51-5 and JESD51-7 at natural convection on 2s2p board. Board with two inner copper layers
(thickness: 35 m) and thermal via array under the exposed pad connected to the first inner copper layer (thickness: 70 m).
