[1] Equivalent to discharging a 150 pF capacitor through a 330  resistor. ESD performance of 6 kV for pins LIN, VBAT and WAKE_N is

verified by an external test house.

[2] Equivalent to discharging a 100 pF capacitor through a 1.5 k resistor.

[3] Equivalent to discharging a 200 pF capacitor through a 10  resistor and a 0.75 H coil.

[4] Junction temperature in accordance with IEC 60747-1. An alternative definition is: Tj = Tamb + P  Rth(j-a), where Rth(j-a) is a fixed value.

The rating for Tvj limits the allowable combinations of power dissipation (P) and ambient temperature (Tamb).
