Push-pull four channel driver with diodes

■

600 mA output current capability per channel

■

1.2 A peak output current (non repetitive) per 
channel

■

Enable facility 

■

Overtemperature protection

■

Logical “0” input voltage up to 1.5 V (high noise 
immunity)

■

Internal clamp diodes

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.
