AND APPLICATION The A2557 low-current quad power drivers provide the same protected output driver function as (and are pin compatible with) the UDx254.

A2557 Features

* I 300 mA Output Current per Channel I Independent Over-Current Protection &Thermal Limiting for Each Driver I Output Voltage to 60 V I Output SOA Protection I Fault-Detection Circuitry for Open or Shorted Load I Low Quiescent Current Sleep Mode I Integral Output Flyback/Clamp Diodes I TTL- and 5 V C

A2557 Applications

* with up to 300 mA drive current per channel. They may also be used for driving incandescent lamps in applications where turn-on time is not a concern. Each of the four outputs will sink 300 mA in the on state. The outputs have a minimum breakdown voltage of 60 V and a sustaining voltage of 40 V. A l
