UDN2982LW Description

Short technical summary and product information.

The UDN2982LW from Allegro Microsystems 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 and output currents of -500mA per channel.

 

This device features TTL, DTL, PMOS, or CMOS compatible inputs and transient-protected outputs. It integrates input current limiting resistors and output transient suppression diodes, activated by an active high input. The UDN2982LW is designed to operate within an ambient temperature range of -20°C to 85°C.

 

The UDN2982LW is available in a 20-pin SOICW package, which offers improved thermal characteristics compared to older versions. This surface-mount package is lead (Pb) free with 100% matte-tin leadframe plating, making it suitable for various industrial and electronic applications.

 

Typical loads for this driver include relays, solenoids, lamps, stepper and/or servo motors, print hammers, and LEDs. Its robust design and features make it a versatile component for power management and control circuits.
