Sanken Electric Co., Ltd. Integrated Circuits (ICs) - Power Management (PMIC) - Motor Drivers, Controllers STA7132MC

The STA7132MC is a unipolar 2-phase stepping motor driver IC designed for applications requiring precise motor control. It supports a maximum load voltage of 35 V and a main power supply voltage of up to 46 V, with a normal operating range of 10 to 44 V. The device can handle output currents up to 2.0 A, making it suitable for various motor driving applications. This IC features multiple stepping control options, including full, half, quarter, eighth, and sixteenth-step excitation driving. It incorporates built-in protection circuitry against motor coil opens and shorts, as well as thermal shutdown protection, enhancing reliability during operation. The STA7132MC is packaged in an 18-pin ZIP type configuration, allowing for easy integration into designs. Additionally, the driver includes a self-excitation PWM current control mechanism, which helps reduce power dissipation and motor noise during operation. The device is also designed to be pin-compatible with other variants in the STA7130MC series, providing flexibility for engineers in their design choices.
