L2293Q

Push-pull four channel driver with diodes

Features

channel

immunity)

Description

The device is a monolithic integrated high voltage,

high current four channel driver designed to

accept standard DTL or TTL logic levels and drive

inductive loads (such as relays solenoides, DC

and stepping motors) and switching power

transistors.

To simplify use as two bridges each pair of

channels is equipped with an enable input. A

separate supply input is provided for the logic,

allowing operation at a lower voltage and internal

clamp diodes are included.

This device is suitable for use in switching

applications at frequencies up to 50 kHz.

The L2293Q is assembled in a VFQFPN-32L 5x5

package which has exposed pad available for

heatsinking.
