Special Features
【Description】A3967SLB is a dedicated driver for pwm constant current control micro-step drive two-phase stepper motor. Stepper motor is usually defined as a step Angle or step parameters, the general motor is divided into 200 steps, that is, the step Angle is 1.8 degrees, EasyDriver has a step subdivision function, this drive board is subdivided into 8 subdivisions, that is, each step of the motor is subdivided into 8 small steps, so that it can be more accurate control, This means that the EasyDriver needs 1600 steps to complete a full 360 degree rotation.
【Feature】MS1 and MS2 are the logical input ports for selecting the subdivision resolution of the stepper motor. DIR is the choice of motor running direction. RESET Reset the initial chip value and mask all external outputs. STEP is the pulse input port.
【Definition】OUT1a, OUT1b, OUT2a, and OUT2b are the two pairs of output ports of the h bridge. ENABLE indicates the enable end. SLEEP is the sleep pattern. SENSE1 and SENSE2 are the current detection resistors of h bridge. REF is the reference voltage. GND is logical and power source groudn. RC1 and RC2 are h bridge fixed cutoff time analog inputs.
【Operation】Operating voltage up to 30v, drive current up to 750ma, an a3967slb can drive a two-phase stepper motor, can achieve 8 subdivision drive. The pwm current control circuit inside the chip can be set to slow, fast, and mixed current attenuation modes by applying voltage to the pfd. If the voltage at the pfd is higher than 0.6vdd, the slow attenuation mode is selected. If it is below 0.21vdd, the fast attenuation mode is selected. In between is a mixed attenuation mode.
【Self-protection】The a3967slb also provides complete protection measures, including transient voltage suppression, overheat protection, prevent current through, and undervoltage self-locking functions.
