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 maxi-
mum 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.
Features:
D 330mA Output Current Capability
D Dual Bridge Included
D Power Save
D Single Input Direction Control
D Low Output Saturation Voltage
D Low Supply Current
D Low Input Current
D Compatible with TTL, LSTTL, and 5V CMOS
D Thermal Shutdown
Absolute Maximum Ratings: (TA = +25°C, Note 1 unless otherwise specified)

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 condi-
tions is not guaranteed. Exposing a circuit to its absolute maximum rating for extended peri-
ods of time may affect the device’s reliability.
Note 2. Thermal resistance is as follows:
RthJA1 ≤ +60°C/W (Soldered on a print circuit board)
RthJA2 ≤ +35°C/W (Soldered on a print circuit covered with copper sufficiently)
RthJA3 ≤ +15°C/W (Soldered on Pin4, Pin5, Pin12, and Pin13 with an infinite heat sink)
