Description

The M54687FP is a semiconductor integrated circuit that is capable of directly controlling the rotating direction and

rotating speed of a smallsize bi-directional motor rotating in both forward and reverse directions.

Features

• Capable of controlling the speed in forward and reverse rotating directions

• Capable of controlling the speed in high speed mode

• Large output current drive (IO(max) =700mA)

• Built-in clamp diode

• Flat package (16P2N)

Application

Micro-cassette for phone-answering machine, AV equipment, and other general consumption appliances

Function

The M54687FP is an IC that can control the forward rotation, reverse rotation and speed of small DC brush motor.

For the basic operation of this IC, output modes are selected, as shown in the logic truth table, by entering appropriate

H/L level into the R, L and S inputs.

Two resistances are put between the output pin and the PSC pin and the resistance ratios are appropriately adjusted to

perform the speed control.

In addition to the above, speed control can be done by varying the voltage at VR pin, in the high speed mode.
