(6) Short circuit current should be limited in duration to no more than 10 seconds. See POWER DISSIPATION in Application Information for
more details.
(7) Exceeding limits could result in excessive device current.
(8) This parameter is ensured by design and/or characterization and is not tested in production. The condition of V
CLAMP
= 3V is not
intended for continuous operation; continuous operation with V
CLAMP
= 3V may incur permanent damage to the device.
