NTE7042 Integrated Circuit BiDirectional Motor Driver Description: The NTE7042 is a BiDirectional Motor Drive in a 9Lead SIP type package and generates an output current of 700mA (Max) with 4 output modes of forward rotation, reverse rotation, stop (idling), and brake according to input logic (2 inputs). The GNDs of the logic unit and power unit are isolated. Therefore, the circuit of a reversible, variablespeed motor can be easily composed by adding an electronic governor at the output.
