Part Number : AN44067A
Function : 37V, 2.5A Microstepping Motor Driver
Package : 34 pin Plastic Small Outline Package With Heat Sink
Maker : Panasonic Corporation
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.
