The L9820 is a high side driver from Littelfuse with multiple features, including diagnostic and protection functions, µP compatible enable input and standby mode
The L9820 is a high side driver realized with Multipower-BCD mixed technology. It drives resistive or inductive loads where one side of the load is connected to ground. The device includes an ENABLE input that is TTL compatible, allowing for standby mode operation.
Key features include on-chip thermal protection and short circuit protection. A diagnostic output provides status indications for short circuits, overvoltage shutdown, and thermal shutdown conditions.
