MTD2003F stepper motor control circuit

M TD200 3F two-phase stepper motor driver This circuit uses dual power supplies: stepper
motor driver and power supply v. . (Recommended maximum 27V) and control logic part use power supply
ycc (sv ±5"). It consists of power stage double H-bridge, base drive circuit, current control
PWM circuit, and overheating protection circuit. See Figure 5 11. Its basic characteristics As follows:
    (】) The input terminals are all TTL/CMOS compatible and can be directly connected to CPU.
    (2) The
control are shown in Tables 5 to 11. When input When it is LL or HH, the output is in the off
state to prevent the upper and lower bridge arms from being connected.
