Function
Power Good output: Open drain output which indicate that output voltage has reached
90% of input voltage
Supply Input: Input to the power switch and the supply voltage For the IC
Switch Output: Output of the power switch
Fault Output: Active LO, open drain output which indicates an over current supply under
voltage or over temperature state.

Un datasheet est un document fourni par le constructeur du composant, où figurent toutes les données techniques sur le produit: puissance dissipée, courant maximal, tension de seuil, tension de claquage, température de stockage, etc. Ils sont en général fournis gratuitement, et se présentent très régulièrement sous la forme d'un document pdf.
