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:
D Dual Reversible Motor Drivers Implemented on a Single Chip (Simultaneous Dual Circuit Operation
is Not Possible)
D Minimum External Components Required
D Control Inputs Directly Compatible with CMOS Logic (Protection Resistors are Required if CMOS
Output Voltage Exceeds 5V)
D Internal Motor Driving Power Transistors
D Internal Surge Suppressors
D Internal Thermal Shut–Down Circuit
Applications:
D VCRs
D Tape Decks

Precautions:
1. While the control input pins of the NTE1834 can be directly connected to MOS logic outputs, it is
recommended that you insert a series protection resistor in the range 1kto 10kbetween the
devices.
2. To improve reliability, be sure to temporarily put the device in brake mode before reversing the
direction of rotation of the motor. A brake mode duration of more than 10µs is recommended.
3. The recommended power on sequence is one in which VCC1 (Pin7) is the first turned on and the
last turned off.
