LIN transceiver with integrated voltage regulator
[3] ESD performance of pins LIN and V
BAT
according to IEC 61000-4-2 (150 pF, 330 ) has been verified by an external test house.
[4] Machine Model (MM): according to AEC-Q100-003 (200 pF, 0.75 H, 10 ).
[5] Charged Device Model (CDM): according to AEC-Q100-011 (field induced charge; 4 pF).
[6] Verified by an external test house to ensure pins can withstand ISO 7637 part 2 automotive transient test pulses 1, 2a, 3a and 3b.
[7] Junction temperature in accordance with IEC 60747-1. An alternative definition is: T

, where R
th(j-a)
is a fixed value.
The rating for T

).
9. Thermal characteristics
[1] According to JEDEC JESD51-2 and JESD51-3 at natural convection on 1s board.
[2] 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 package connected to the first inner copper layer.
