NTE1834
Integrated Circuit
Dual Reversible Motor Driver
Description:
The NTE1834 is a monolithic IC in a 10鈥揕ead SIP type package designed for use as a dual reversible
motor driver. This device contains two independent circuits designed for driving brush鈥搕ype DC mo-
tors. The control logic inputs are compatible with CMOS devices. The motor torque can be controlled
by varying the motor voltage with the control input (Pin8). With few external components required
and dual circuit configuration, the NTE1834 offers great benefits in terms of reduced components and
reduced circuit board space.
