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

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)
