UDN2982LW-T

Power Distribution Switches, Load Drivers Overview

The UDN2982LW-T is an obsolete 8-channel source driver manufactured by Allegro MicroSystems. It provides high-current switching for loads up to 50V with a maximum output current of 500mA per channel. The device features fixed current limiting and operates within a temperature range of -20°C to 85°C. Packaged in a 20-SOIC surface-mount format, it interfaces low-level logic to high-current applications without requiring a separate supply voltage.

Power Distribution Switches, Load Drivers Feature Summary

Integrates eight independent high-side bipolar drivers for interfacing logic signals to high-current loads
Incorporates fixed current limiting protection to safeguard against overcurrent conditions
Operates as a non-inverting interface requiring no external supply voltage for control logic

Power Distribution Switches, Load Drivers Applications

Relay driving circuits
Solenoid actuation systems
Lamp load switching
