2557 - PROTECTED QUAD LOW-SIDE DRIVER

General Description

The A2557 low-current quad power drivers provide the same protected output driver function as (and are pin compatible with) the UDx2543/49/59 devices, combined with a fault diagnostic scheme similar to the UDx2547, plus an automatic low-current Sleep-Mode function.

Key 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 CMOS-Compatible Inputs Complete part number includes a suffix to identify operating temperature range (E-, K-, or S-) and package type (-B, -EB, or -LB). Always order by complete part number, e. g. , A25.
