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.
