M54543AFP
Bi-DIRECTIONAL MOTOR DRIVER
WITH BRAKE FUNCTION AND THERMAL SHUT DOWN FUNCTION
DESCRIPTION
The M54543AFP is a semiconductor integrated circuit that is
capable of directly driving a smallsize bi-directional motor rotating
in both forward and reverse directions.
FEATURES
qWide range of operating voltage (VCC=4 – 15V)
qPossible direct driving with TTL, PMOS and CMOS IC outputs
qSmall outline (10-pin SOP)
qLow output saturation voltage (large voltage across motors)
qBuilt-in clamp diode
qLarge output current drive (IO(max) = ±700mA)
qProvided with brake function
qBuilt-in thermal shutdown protection circuit
APPLICATION
Sound equipment such as tape deck and radio cassette, VTR, and
other general consumer appliances
