PROTECTED QUAD POWER DRIVER

Providing interface between low-level logic and power loads, the UDK/UDN/UDQ2547B and UDK/UDN/UDQ2547EB quad power drivers combine logic gates and high-current bipolar outputs with

complete output protection. Each of the four outputs will sink 600 mA in the ON state. The outputs have a minimum breakdown voltage (load dump) of 60 V and a sustaining voltage of 40 V. The inputs are compatible with TTL and 5 V CMOS logic systems and include internal pull-down resistors to ensure that the outputs remain OFF if the inputs are open-circuited.

FEATURES

■ Output SOA Protection

■ Low Output-Saturation Voltage

■ Diagnostic FAULT Output

■ TTL and 5 V CMOS Compatible Inputs

■ Independent Over-Current Protection for Each Driver

■ Independent Thermal Protection for Each Driver

■ 600 mA Output Current per Channel
