The Allegro Microsystems UDK2559LB is a quad power driver designed for applications requiring robust output current control and protection. Each of its four outputs can sink 700 mA, with independent overcurrent protection activated at approximately 1 A to safeguard against short circuits.
This device offers a minimum breakdown voltage of 60 V under load dump conditions and a sustaining voltage of 40 V. The inputs are compatible with TTL and 5 V CMOS logic systems. Integral flyback diodes are included for inductive load protection.
Packaged in a 16-lead wide-body SOIC (SOICW) for surface-mount applications, the UDK2559LB operates across a temperature range of -40°C to 125°C. Its design includes thermal limiting circuits for both the device and individual drivers, ensuring reliable operation under fault conditions. It can drive loads such as incandescent lamps, relays, solenoids, and DC stepping motors.
