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.
