Power Distribution Switches, Load Drivers

L295 Description

The L295 from STMicroelectronics is a bipolar high-side power driver designed for controlling relays and solenoids in demanding industrial and automotive applications. This obsolete but robust IC operates within a 4.75V to 10V supply range and delivers a maximum output current of 2A, making it suitable for driving inductive loads up to 46V. Housed in a 15MULTIWATT through-hole package, the L295 features a 1:2 input-to-output ratio with two independent outputs, enabling flexible load management. Its on/off interface simplifies control logic, while over-temperature protection ensures reliable operation under harsh conditions.

L295 Features

• Bipolar High-Side Driver: Optimized for driving inductive loads like relays and solenoids.
• Wide Load Voltage Range (12V–46V): Supports diverse industrial and automotive systems.
• 2A Output Current: Capable of handling high-current loads without external amplification.
• Over-Temperature Protection: Safeguards against thermal overload, enhancing durability.
• 1:2 Input-to-Output Ratio: Allows one control signal to manage two outputs efficiently.
• Through-Hole Mounting (15MULTIWATT): Facilitates robust mechanical integration in legacy designs.
• ROHS3 Compliant & REACH Unaffected: Meets environmental and regulatory standards.

L295 Applications

• Automotive Systems: Ideal for controlling solenoids in fuel injection, transmission, or HVAC systems.
• Industrial Automation: Drives relays in PLCs, motor controllers, and power distribution units.
• Legacy Equipment Maintenance: Suitable for repairing or upgrading older systems requiring through-hole components.
• High-Voltage Switching: Used in applications demanding reliable switching of inductive loads up to 46V.

Conclusion of L295

The L295 stands out for its high-current capability, wide voltage range, and robust protection features, making it a dependable choice for driving inductive loads in harsh environments. While marked as obsolete, its through-hole package and simplified control interface retain relevance in legacy and niche applications. Engineers valuing durability and ease of integration may still find the L295 advantageous for specific high-power switching tasks.
