MITSUBISHI M54544L Bi-DIRECTIONAL MOTOR DRIVER WITH BRAKE FUNCTION 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. PIN CONFIGURATION (TOP VIEW) Power supply 1 VCC1 VCC’1 O2 IN1 GND 1 2 3 FEATURES q Wide range of operating voltage (VCC=4 – 16V) q Possible direct driving with TTL, PMOS and CMOS IC outputs q Low output saturation voltage (large voltage across motors) q Built-in clamp diode q Large output current drive (IO(max) = ±1.2A) q Provided with brake function Output power supply 1 Output 2 Input 1 M54544L 4 5 6 7 8 9 Input 2 Output 1 IN2 O1 VCC’2 VCC2 APPLICATION Sound equipment such as tape deck and radio cassette, VTR, and other general consumer appliances Output power supply 2 Power supply 2 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...
