PWM Chopper-Type Bipolar Driver IC for Stepping Motor Control

Features

• Single-chip motor driver for sinusoidal microstep control of

stepping motors

• High output withstand voltage due to the use of BiCD process:

Ron (upper and lower sum) = 0.7 Ω (typ.)

• Forward and reverse rotation

• Selectable phase excitation modes (2, 1-2, 2W1-2 and 4W1-2)

• High output withstand voltage: VDSS = 40 V

• High output current: IOUT = 2.5 A (peak)

• Packages: QFN48-P-0707-0.50

• Internal pull-down resistors on inputs: 100 kΩ (typ.)

• Output monitor pin: MO current (IMO (max) = 1 mA)

• Reset and enable pins

• Thermal shutdown (TSD)
