FUNCTION
The M54543AFP 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 (VCC) to the control circuit and the power supply
(VCC’) for output are independently provided. The rotating speed of
the motor can be therefore changed by using VCC and VCC’as
different power supplies and by making VCC or VCC’ variable.
In addition, built-in thermal protection circuit protects the IC from
thermal destruction in case of abnormal condition such as motor
blocking.
