Bi-DIRECTIONAL MOTOR DRIVER
WITH BRAKE FUNCTION AND THERMAL SHUT DOWN FUNCTION
M54544AL
MITSUBISHI <CONTROL / DRIVER IC>
PIN CONFIGURATION (TOP VIEW)
DESCRIPTION
The M54544AL is a semiconductor integrated circuit that is
capable of directly driving a smallsize bi-directional motor rotating
in both forward and reverse directions.
FEATURES
G
Wide range of operating voltage (V
CC
=4 – 16V)
G
Possible direct driving with TTL, PMOS and CMOS IC outputs
G
Low output saturation voltage (large voltage across motors)
G
Built-in clamp diode
G
Large output current drive (I
O
(
max
)=
±
1.5A)
G
Provided with brake function
G
Built-in thermal shutdown protection circuit
APPLICATION
Sound equipment such as tape deck and radio cassette, VTR, and
other general consumer appliances
FUNCTION
The M54544AL is an IC for driving a smallsize bi-directional motor
that rotates in both forward and reverse directions. When both
inputs 1 and 2 are set to low-level, outputs 1 and 2 are set to
“OFF”. When input 1 is set to high-level and input 2 is set to low-
level, output 1 is set to high-level and output 2 is set to low-level
(forward rotation status). When input 1 is set to low-level and input
2 is set to high-level, output 1 is set to low-level and output 2 is set
to high-level (reverse rotation). When both inputs 1 and 2 are set to
high-level, both outputs 1 and 2 are set to low-level (brake status).
The power supply (V
CC
) to the control circuit and the power supply
(V
CC
’) for output are independently provided. The rotating speed of
the motor can be therefore changed by using V
CC
and V
CC
’ as
different power supplies and by making V
CC
or V
CC
’ variable.
If the motor resistance is high (light load and small driving current:
tens of mA), and V
CC
is larger than V
CC
’, current does not flow
backward from the V
CC
pin to V
CC
’ pin.
