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:
●Wide range of operating voltage (VCC=4 – 16V)●Possible direct driving with TTL, PMOS and CMOS IC outputs●Low output saturation voltage (large voltage across motors)●Built-in clamp diode●Large output current drive (IO(max)=±1.5A)●Provided with brake function●Built-in thermal shutdown protection circuit
