(1)

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

which the device is intended to be functional, but do not ensure specific performance limits. For ensured specifications and conditions

see the Electrical Characteristics.

(2)

If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and

specifications.

(3)

The GATE pin voltage is typically 12V above VIN when the LM5069 is enabled. Therefore the Absolute Maximum Ratings for VIN

(100V) applies only when the LM5069 is disabled, or for a momentary surge to that voltage since the Absolute Maximum Rating for the

GATE pin is also 100V.

(4)

The human body model is a 100 pF capacitor discharged through a 1.5 k

Ω resistor into each pin.
