DESCRIPTION
The L9820 High Side Driver realized with Multipower - BCD mixed technology, drives resistive
or inductive loads with one side connected to
ground.
The ENABLEinput is TTL compatibleand a diagnostic outputprovides an indicationof short circuit
and device status (thermal and overvoltage shutdown).Onchip thermal protection and short circuit
protectionare provided.
