NCV8461
Self Protected High Side
Driver with Temperature
Shutdown and Current Limit
The NCV8461 is a fully protected High−Side driver that can be used
to switch a wide variety of loads, such as bulbs, solenoids and other
activators. The device is internally protected from an overload
condition by an active current limit and thermal shutdown. A
diagnostic output reports OFF state open load conditions as well as
thermal shutdown.
Features
• Short Circuit Protection
• Thermal Shutdown with Automatic Restart
• CMOS (3 V / 5 V) Compatible Control Input
• Off State Open Load Detection
• Open Drain Diagnostic Output
• Overvoltage Protection
• Undervoltage Shutdown
• Loss of Ground and Loss of VD Protection
• ESD Protection
• Reverse Battery Protection (with external resistor)
• Very Low Standby Current
• AEC−Q100 Qualified

Typical Applications
• Switch a Variety of Resistive, Inductive and Capacitive Loads
• Can Replace Electromechanical Relays and Discrete Circuits
• Automotive / Industrial

3. Not subjected to production testing
4. To ensure long term reliability under heavy overload or short circuit conditions, protection and related diagnostic signals must be used
together with a proper hardware/software strategy. If the devices operates under abnormal conditions this hardware/software solutions
must limit the duration and number of activation cycles.
