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 signalfrom an optocoupleror a pulse transformer. It filters parasitic inputsignals and drives any MOS or IGBT.
