AN44067A datasheet

Description :

AN44067A is a two channel H-bridge driver LSI. Bipolar stepping motor can be controlled by a single driver LSI.

2 phase excitation, half- step, 1-2 phase excitation, W1-2 phase excitation and 2W1-2 phase excitation can be selected.

 Application Circuits :


• PMW can be driven by built-in CR (3-value can be selected during PWM OFF period.) Selection during PWM OFF period enables the best PWM drive.

• Mix Decay compatible (4-value for Fast Decay ratio can be selected.) Mix Decay control can improve accuracy of motor current wave form.

• Built -in low voltage detection If supply voltage lowers less than the range of operating supply voltage, low voltage detection operates and all phases of motor drive output are turned OFF.
