UDN2559EB Description

Short technical summary and product information.

The UDN2559EB from Allegro Microsystems is a quad power driver IC designed for efficient power management applications. It combines AND logic gates with high-current bipolar outputs, offering complete output protection.

 

Each of the four outputs can sink 700 mA in the on state. The device features a minimum breakdown voltage (load dump) of 60 V and a sustaining voltage of 40 V. Its inputs are compatible with TTL and 5 V CMOS logic systems. For enhanced reliability, the UDN2559EB includes independent overcurrent protection for each channel, activated at approximately 1 A, and thermal protection for both the device and individual drivers.

 

This power driver IC is capable of driving various loads, including incandescent lamps, relays, solenoids, and DC stepping motors. It is housed in a 28-lead PLCC surface mount package, facilitating integration into compact designs. The operating temperature range is -20°C to 85°C (TA).

 

Key features include low output-saturation voltage and integral output flyback diodes, making it a versatile solution for applications requiring robust load driving capabilities with built-in protection.
