The Allegro Microsystems UDN2982LW-T is an 8-channel source driver IC designed for interfacing between low-level logic and high-current loads. It is suitable for high-side switching applications and supports load supply voltages up to 50V with output currents 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 UDN2982LW-T features transient-protected outputs and an output breakdown voltage of up to 50V.
Packaged in a 20-pin SOICW (wide body) package, it offers improved thermal characteristics compared to older 18-pin SOIC versions. The package is lead (Pb) free with 100% matte-tin leadframe plating. The operating temperature range is -20°C to 85°C.
Typical applications include driving relays, solenoids, lamps, stepper motors, servo motors, print hammers, and LEDs. Its robust design and integrated protection features make it a reliable choice for various industrial and consumer electronics.
