UDN2982A Description

Short technical summary and product information.

The Allegro Microsystems UDN2982A is an 8-channel source driver IC suitable for interfacing between low-level logic and high-current loads. It is designed for high-side switching applications and supports load supply voltages ranging from 5V to 50V, with an output current capability of up to 500mA per channel.

 

This device is compatible with 5V logic systems including TTL, Schottky TTL, DTL, and 5V CMOS. It integrates input current limiting resistors and output transient suppression diodes, and is activated by an active-high input. The UDN2982A is available in an 18-DIP package, which is through-hole mountable.

 

Typical applications for the UDN2982A include driving loads such as relays, solenoids, lamps, stepper and servo motors, print hammers, and LEDs. Its transient-protected outputs and current limiting features enhance reliability in demanding applications.
