The Allegro Microsystems UDN2982LWTR-T 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 designed for high-side switching applications and benefits from separate logic and load grounds. It is compatible with 5V logic systems, including TTL, Schottky TTL, DTL, and 5V CMOS. The outputs are transient-protected, and the device integrates input current limiting resistors.
The UDN2982LWTR-T comes in a 20-pin wide-body SOIC package, offering improved thermal characteristics compared to older versions. The package is lead (Pb) free with 100% matte-tin leadframe plating. It operates within an ambient temperature range of -20°C to 85°C.
Typical applications include driving relays, solenoids, lamps, stepper motors, servo motors, print hammers, and LEDs. The device is activated by an active-high input and features fixed current limiting for fault protection.
