UDQ2559B - PROTECTED QUAD POWER DRIVER

Download the UDQ2559B datasheet PDF. This datasheet also covers the UDQ2559 variant, as both devices belong to the same protected quad power driver family and are provided as variant models within a single manufacturer datasheet.

General Description

Providing improved output current limiting, the UDK, UDN, and UDQ2559B, EB, and LB quad power drivers combine AND logic gates and high-current bipolar outputs with complete output protection.

Each of the four outputs sink 700 mA in the on state.

Key Features

  • 700 mA output current per channel.
  • Independent overcurrent protection for each driver.
  • Thermal protection for device and each driver.
  • Low output-saturation voltage.
  • Integral output flyback diodes.
  • TTL and 5 V CMOS-compatible inputs Packages: 16-pin DIP with exposed thermal tabs (B package) 28-pin PLCC (Package EB) Not to scale 16-pin SOICW with internally fused pins (LB package).
