ESD performance of pins CANH and CANL according to IEC 61000-4-2 (150 pF, 330

Ω)

has been be verified by an external test house.

The result is equal to or better than

±8

kV (unaided).

Human Body Model (HBM): according to AEC-Q100-002 (100 pF, 1.5 kΩ).

Machine Model (MM): according to AEC-Q100-003 (200 pF, 0.75

µH,

10

Ω).

Charged Device Model (CDM): according to AEC-Q100-011 (field Induced charge; 4 pF). The classification level is C5 (>1000 V).

In accordance with IEC 60747-1. An alternative definition of virtual junction temperature is: T

vj

= T

amb

+ P

×

R

th(vj-a)

, where R

th(vj-a)

is a

fixed value to be used for the calculation of T

vj

. The rating for T

vj

limits the allowable combinations of power dissipation (P) and ambient

temperature (T

amb

).
