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 microprocessor logic levels at the
inputs and can drive 2 solenoids. The output current
is completely controlled by means of a switch-

ing 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.
