SLA7080MPR [SANKEN]

The SLA7080M series are unipolar 2-phase stepping motor driver ICs featuring four output current levels (1, 1.5, 2, and 3 A) with built-in sense resistors for motor current detection. They incorporate self-excitation PWM control with fixed off-time, synchronous rectifying circuit to reduce losses, and synchronous PWM function to prevent noise in motor Hold mode. The devices include sleep function for power reduction, protection against motor coil open/short circuits and overheating, and externally-adjustable blanking time (3.2 μs / 5.2 μs). The multichip structure enhances thermal dispersion in a compact ZIP 23-pin molded package.
