Bi-Directional Motor Driver with Brake Function

REJ03F0043-0100Z

Rev.1.0

Sep.19.2003

Description

The M54641 is a semiconductor integrated circuit that is capable of directly driving a smallsize bi-directional motor

rotating in both forward and reverse directions.

Features

•

Wide range of operating voltage (V_CC= 4 – 10V,V_CC’(max) = 20V)

Low output saturation voltage in stationary motor circuit (largevoltage across motors)

Built-in clamp diode

Provided with output voltage control pin (V_Z)

Built-in thermal shutdown circuit (Tj(shut) = 120°C standard)

Application

Sound equipment such as tape deck and radio cassette, and VTR

Function

The M54641 is an IC for driving a smallsize bi-directional motor that rotates in both forward and reverse directions.

Giving signal to inputs IN1 and IN2 outputs the signal of the same phase to output pins O1 and O2. That is, giving

high-level signal to input IN1 and low-level signal to input IN2 sets output O1 to high-level and output O2 to low-level.

Connection of a motor between output pins O1 and O2 uses O1 as an output current source and O2 as an output current

sink to rotate the motor. In addition, giving the reverse signal to inputs IN1 and IN2 sets O1 and O2 to low-level and

high-level, respectively, resulting in rotating the motor reversely.

However, when both IN1 and IN2 are set to “H”, both O1 and O2 are set to low-level, resulting in sudden stop of motor

rotation. (Brake mode)

If the Zener diode of certain voltage, for example, is added to the V_Zpin, the output “H” voltage does not rise over the

Zener voltage and the motor rotates at constant speed.

If the V_Zpin is connected to the output power supply V_CC’ pin, the rotating speed of the motor can be varied by varying

the V_CC’ voltage.

The motor rush current and the current with the motor put in stationary status are as follows: Iop(max) = 800mA and

I_O(max) = 150mA.
