Integrated Circuit
2–Phase Stepping Motor Driver
Description:
The NTE7005 monolithic power IC is a dual bridge driver in a 16–Lead DIP type package. The maximum driving current and voltage is 330mA x 12V per bridge. Therefore, the best use for this part is
in a two–phase bipolar stepping motor driving the head actuator of a 3, to 5.25–inch Floppy Disk Drive.

Note 1. The absolute maximum ratings are limiting values, to be applied individually, beyond which
the device may be permanently damaged. Functional operation under any of these conditions is not guaranteed. Exposing a circuit to its absolute maximum rating for extended periods of time may affect the device’s reliability.
Note 2. Thermal resistance is as follows:
R
1 ≤ +60°C/W (Soldered on a print circuit board)
