L295

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.
