NTE1834
Integrated Circuit
Dual Reversible Motor Driver
Description:
The NTE1834 is a monolithic IC in a 10–Lead SIP type package designed for use as a dual reversible
motor driver. This device contains two independent circuits designed for driving brush–type 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.
Features:
Dual Reversible Motor Drivers Implemented on a Single Chip (Simultaneous Dual Circuit Operation
is Not Possible)
Minimum External Components Required
Control Inputs Directly Compatible with CMOS Logic (Protection Resistors are Required if CMOS
Output Voltage Exceeds 5V)
Internal Motor Driving Power Transistors
Internal Surge Suppressors
Internal Thermal Shut–Down Circuit
Applications:
VCRs
Tape Decks
