NTE7042
Integrated Circuit
Bi–Directional Motor Driver
Description:
The NTE7042 is a Bi–Directional Motor Drive in a 9–Lead 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, variable–speed motor can be easily composed by adding an
electronic governor at the output.
