General Description

The LM18298 is a high voltage, high current dual full-bridge driver designed to accept standard TTL logic levels and drive inductive loads such as relays, solenoids, DC and stepping motors. Two enable inputs are provided to gate the input control signals.

The emitters of the lower transistors of each bridge are connected together and the corresponding external terminal can be used for the connection of a current sensing resistor. An additional supply input is provided to accommodate conventional logic supply voltages.
