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 1k
to 10k
between 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 10
μ
s is recommended.
3. The recommended power on sequence is one in which V
CC
1 (Pin7) is the first turned on and the
last turned off.
