[ Alternative : SLA7082MPR]
SLA7082MS
2-phase stepper motor unipolar IC, self excitation PWM current control with fixed off time. The built-in current sense resistor allows reduction of external components. The series has a built-in protection function which operates during abnormal operation (motor coil opens/shorts ) and thermal shutdown protection as well. Lineup with various rated currents and are also available.
Features
-
・Power supply voltages VBB:
46V(max), normal operating range: 10V to 44V ・Logic supply voltages VDD: 3.0V to 5.5V ・Maximum output current Io: 2A ・Supports phase input （Supports Full step / Half Step） ・Built-in current sense resistor ・PWM current control with fixed OFF time ・Blanking time can be selected（3.2µs or 5.2µs） ・Synchronous PWM chopping function prevents motor
