More Specifics:

• High-side smart power switch utilizing STMicroelectronics' proprietary VIPower™ technology for robust and efficient load driving.
• Very low on-resistance (50mΩ max) minimizes power dissipation and voltage drop across the switch.
• Capable of delivering up to 2.8A continuous current, suitable for driving resistive, inductive, and capacitive loads.
• Built-in protection features: fixed current limiting (prevents short-circuit damage) and over-temperature shutdown with auto-restart (cyclic thermal protection).
• Status flag output provides diagnostic response to the microcontroller (open-drain) for fault indication.
• Wide operating voltage range (10V to 36V) makes it compatible with automotive, industrial, and general-purpose power systems.
• Non-inverting input with simple on/off control (TTL/CMOS compatible).
• Through-hole Pentawatt package with straight leads for easy mounting on PCBs and prototyping.
• Ideal for driving lamps, solenoids, DC motors, and resistive loads in harsh environments.

About STMicroelectronics VIPower™ High-Side Drivers:STMicroelectronics is a global leader in semiconductor solutions, and their VIPower™ (Vertical Intelligent Power) technology integrates power switches with smart protection and diagnostic features on a single chip. These devices are designed to replace discrete components (relays, fuses, discrete MOSFETs) in automotive and industrial applications, providing improved reliability, reduced space, and enhanced diagnostics.
The VN540 is a single-channel high-side driver that can switch a load with currents up to 2.8A under voltages from 10V to 36V. Its 50mΩ on-resistance ensures efficient power delivery, while the built-in current limit and thermal protection safeguard both the IC and the load. The status flag output allows external monitoring for fault conditions, enabling system-level error handling.
Common applications include automotive body electronics (lights, motors, actuators), industrial automation (solenoid drivers, valve control), power distribution modules, and any system requiring protected high-side switching in medium-current environments.
Please verify the voltage range, current capability, package type, and logic levels before purchasing to ensure compatibility with your specific application. Note that this part is obsolete but available as new old stock, and it remains fully functional and reliable for new designs where the part is still suitable.
