SLA7083MPR [SANKEN]

The SLA7080M series are unipolar 2-phase stepping motor driver ICs with a multichip structure for enhanced thermal dispersion. They feature a power supply voltage (VBB) up to 46 V (normal operating range 10 to 44 V) and logic supply voltage (VDD) from 3 to 5.5 V. Four output current options are available: 1 A, 1.5 A, 2 A, and 3 A. The ICs support stepping control for phase input (full or half step) and include built-in sense resistors for motor current detection. They utilize self-excitation PWM control with fixed off-time and include a synchronous rectifying circuit to reduce losses. Additional features include a synchronous PWM function to prevent noise in motor hold mode, a sleep function to reduce power consumption in standby mode, and protection circuits for motor coil open/short detection and overheating prevention. The device comes in a compact 23-pin ZIP molded package (SLA package).
