Features
・BiCD process integrated monolithic IC. ・Capable of controlling 1 bipolar stepping motor. ・PWM controlled constant-current drive. ・Allows full, half, quarter step operation. ・Low on-resistance (High + Low side=0.49Ω(typ)) MOSFET
output stage. ・High efficiency motor current control mechanism (Advanced
Dynamic Mixed Decay) ・High voltage and current (For specification, please refer to absolute
maximum ratings and operation ranges) ・Built-in error detection circuits (Thermal shutdown (TSD), over-current
shutdown (ISD), and power-on reset (POR)) ・Built-in VCC
regulator for internal circuit use. ・Chopping frequency of a motor can be customized by external resistance
and condenser. ・Multi package lineup
