NCV8452
Self Protected High Side
Driver with Temperature
Shutdown and Current Limit
The NCV8452 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.
Features
• Short Circuit Protection
• Thermal Shutdown with Automatic Restart
• CMOS (3 V/5 V) Compatible Control Input
• Overvoltage Protection and Shutdown
• Output Voltage Clamp for Inductive Switching
• Under Voltage Shutdown
• Loss of Ground Protection
• ESD Protection
• Reverse Battery Protection (with external resistor)
• Very Low Standby Current
• NCV Prefix for Automotive and Other Applications Requiring
Unique Site and Control Change Requirements; AEC−Q100
Qualified and PPAP Capable
• These are Pb−Free Devices
Typical Applications
• Switch a Variety of Resistive, Inductive and Capacitive Loads
• Can Replace Electromechanical Relays and Discrete Circuits
• Automotive / Industrial

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
