IC L295 : Switch-Mode Solenoid Driver

The L295 is a monolithic integrated circuit in a 15-lead Multiwatt ® package; it incorporates all the functions for direct interfacing between digital circuitry and inductive loads. The L295 is designed to accept standard microprocessor logic levels at the inputs and can drive 2 solenoids. The output current is completely controlled using a switching technique allowing very efficient operation.  Furthermore, it includes an enable input and dual supplies (for interfacing with peripherals running at a higher voltage than the logic). The L295 is particularly suitable for applications such as hammer driving in matrix printers, step motor driving, and electromagnet controllers.

Features:-

• HIGH CURRENT CAPABILITY (up to 2.5A per channel).
• HIGH VOLTAGE OPERATION (up to 46V for power stage).
• HIGH EFFICIENCY SWITCHMODE OPERATION.
• REGULATED OUTPUT CURRENT (adjustable).
• FEW EXTERNAL COMPONENTS.
• SEPARATE LOGIC SUPPLY.
• THERMAL PROTECTION.
