■ Overview
The AN6663S and AN6663SP are the forward/reverse drive
ICs for small DC motors. They provide 4 Kinds of outputs such
as foward rotation, reverse rotation, brake, and stop by the 2bit
input and are optimum as the drivers for the small motors of
100 to 150mA.
■ Features
•
Wide range of operating supply voltage
: V
CC (opr)
= 3 to 16V
•
Large power dissipation
(AN6663SP : PD = 1.45W when mounted)
•
Built-in low saturation voltage type output transistor
•
Built-in counter electromotive voltage suction diode
•
Input voltage at the TTL level : V
IL
= 0.8V or less,
V
IH
= 2V or more
