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
