DESCRIPTION
The L295 is a monolithic integrated circuit in a 15
-lead Multiwatt® package; it incorporates all the
functions for direct interfacing between digital cir-
cuitry and inductive loads.
The L295 is designed to accept standard micro-
processor logic levels at the inputs and can drive
2 solenoids. The output current is completely con-

trolled by means of a switch-ing technique allow-
ing 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.
