DESCRIPTION

The L6353 device is a smart driver, with all the

drive and protection know-how ”on board”.

Available in both DIP and SO package, it can be

triggered with a logic level or with the signal from an

optocoupler or a pulse transformer. It filters parasitic

input signals and drives any MOS or IGBT.
