[1] All voltages are defined with respect to pin GND, unless otherwise specified. Positive current flows into the

device.

[2] Only relevant if VWAKE < VGND − 0.3 V; current will flow into pin GND.

[3] Junction temperature in accordance with “IEC 60747-1”. An alternative definition is: Tvj = Tamb + P × Rth(vj-a)

where Rth(vj-a) is a fixed value to be used for the calculation of Tvj. The rating for Tvj limits the allowable

combinations of power dissipation (P) and ambient temperature (Tamb).

[4] Equivalent to discharging a 100 pF capacitor through a 1.5 kΩ resistor.

[5] Equivalent to discharging a 200 pF capacitor through a 10 Ω resistor and a 0.75 µH coil.
