FD115MA Datasheet | Feeling Technology

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 Built-in RD((Rotation Detect)) signal output Available in SIP-5L, SOT89-5L packages For 12V systems FD115MH FD115MA Smart motor driver with embedded Hall sensor Halogen Free General Description FD115MH/FD115MA 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 bine to provide a plete protecting scenario for the motor system, keep the motor system from possible damages and guarantee correct operations.
