UDN2982LWTR Description

Short technical summary and product information.

The Allegro MicroSystems UDN2982LWTR is an 8-channel source driver suitable for interfacing between low-level logic and high-current loads. It supports load supply voltages up to 50V and provides an output current of up to -500mA per channel.

 

This device is compatible with 5V logic systems, including TTL, Schottky TTL, DTL, and 5V CMOS. It features transient-protected outputs and input current limiting resistors. The UDN2982LWTR is activated by an active high input.

 

Packaged in a 20-pin SOICW, this component is designed for surface mounting. It offers improved thermal characteristics compared to older versions and is pin-compatible. The package is lead (Pb) free with 100% matte-tin leadframe plating.

 

Typical applications include driving relays, solenoids, lamps, stepper motors, servo motors, print hammers, and LEDs. The device integrates input current limiting resistors and output transient suppression diodes.
