BiCD Constant-Current Two-Phase Bipolar Stepping Motor Driver IC

Features

• BiCD process monolithic IC

• Capable of controlling bipolar stepping motor

• PWM controlled constant-current drive without resistance for motor current detection

• Built-in ACDS (Advanced Current Detect System) function enables a PWM constant current

control without external current detection resistors.

• Built-in ADMD(Advanced Dynamic Mixed Decay) function enables a high efficiency PWM

constant current control.

• I/F: Capable of switching between the phase input control and the clock input control

• Full-step/Half-step/Quarter-step resolutions

• BiCD: DMOSFET is adopted to output power transistor.

• High withstand voltage and large current: 40 V / 3.0 A (absolute maximum ratings)

• Built-in thermal shutdown detection (TSD), Over current detection (ISD), and Under voltage

lockout detection(UVLO)

• Decreasing number of external components by reducing charge pump

• Package: P-VQFN36-0505-0.50-002
