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 lowlevel (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). Th...
