FD1157H  Smart motor driver with embedded Hall sensor General Description Download 　FD1157H is a two coil motor driver with embedded Hall sensor. It integrates the motor driver with the Hall sensor, which simplifies the PCB(printed circuit board) design and make the fabrication of small-size motors possible.  Lock-shutdown and auto-restart function keeps the motor from being over-heated and restarts the motor after being locked. “Soft-switch” phase-switching technique is used to reduce the vibration and acoustic noise. Thermal-shutdown protection ensures the motor driver to operate under specified temperature ranges.  All the protection mechanisms mentioned above combine to provide a complete protecting scenario for the motor system, keep the motor system from possible damages and guarantee correct operations. 　 ˙Data Sheet Features ˙Motor driver with integrated Hall sensor ˙Lock-shutdown protection & auto-restart function ˙Precise magnetic switching thresholds ˙“Soft-switch” phase-switching technique to reduce vibration and acoustic noise ˙Thermal shutdown protection ˙Available in SIP-4L packages ˙For 12V systems
