DUAL SWITCH-MODE SOLENOID DRIVER

PRELIMINARY DATA

HIGH CURRENT CAPABILITY (up to 2.5A per

channel)

HIGH VOLTAGE OPERATION (up to 46V for

power stage)

Multiwatt 15

HIGH EFFICIENCYSWITCHMODE OPERATION

REGULATED OUTPUT CURRENT (adjustable)

FEW EXTERNAL COMPONENTS

SEPARATE LOGIC SUPPLY

ORDER CODE : L295

THERMAL PROTECTION

DESCRIPTION

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.

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 andcan drive2solenoids. Theoutputcurrent

is completely controlled by means of a switch-
