Bi-DIRECTIONAL MOTOR DRIVER WITH BRAKE FUNCTION
M54544L
MITSUBISHI <CONTROL / DRIVER IC>
PIN CONFIGURATION (TOP VIEW)
DESCRIPTION
The M54544L 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
) =
±
1.2A)
G
Provided with brake function
APPLICATION
Sound equipment such as tape deck and radio cassette, VTR, and
other general consumer appliances
FUNCTION
The M54544L 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 resistance of the motor is high (light load and small drive
current: tens of mA), and V
CC
is larger than V
CC
’, current does not
flow backward from the V
CC
pin to the V
CC
’ pin.
