Unipolar 2-Phase Stepping Motor Driver

SLA7080MPR Series Unipolar 2-Phase Stepping Motor Driver ICs FEATURES AND BENEFITS • Power supply voltage, VBB, 46 V maximum; 10 to 44 V normal operating range • Logic supply voltage, VDD, 3 to 5.5 V • Four output currents, IO(max), options: 1, 1.5, 2, and 3 A • Stepping control for phase input (full or half step) • Built-in sense resistor detects motor current • Compact ZIP 23-pin molded package (SLA package) • Self-excitation PWM control with fixed off-time • Built-in synchronous rectifying circuit reduces losses at PWM-off • Synchronous PWM function prevents noise generation in motor Hold mode • Sleep function reduces power consumption of drivers in Standby mode • Protection circuit detects motor coil open/short and prevents overheating due to avalanche breakdown • Externally-adjustable (3.2 μs /5.2 μs) blanking time (minimum on-time) PACKAGE: 23-pin ZIP (type SLA) DESCRIPTION This document describes the function and features of the SLA7080MPR series, which are unipolar 2-phase stepping motor driver ICs. Four levels of output current are available from the incorporated MOSFETs, corresponding to the rated output current ratings. All current ratings are available with protection against motor coil shorts or motor open wire detection. The SLA7080MPR series has a multichip structure for enhanced thermal dispersion. The Control IC (MIC), four power elements (MOSFET), and dual sense resistors, are all separate ICs. Built-in sense resistors for each phase allow accurate tracki.
