Overview
FEELING TECHNOLOGY Features Motor driver with high sensitivity Hall-effect sensor H-Bridge MOS driver Lock-shutdown protection & auto-restart function “Soft-switch” phase-switching technique to reduce vibration and acoustic noise Thermal shutdown protection(TSD) Available in SIP-4L package For 12V or 24V DC motor / FAN systems FD2257H Smart motor driver with embedded Hall sensor Halogen Free General Description FD2257H is a single-phase full wave motor driver with embedded Hall-effect sensor IC.
It integrates a H-bridge MOS driver, a high sensitivity hall-effect sensor, an event timer for rotor locked in SIP-4L package, which make the motors’ PCBs(printed circuit boards) design easy and fabricate the high efficiency and high voltage DC motors or FANs as simply as possible.
For safety, Lock-shutdown function would turn the IC’s internal drivers off avoiding over-heat when the rotor is locked, and IC will try to re-start the rotor’s torque after the time of these drivers’ shutdown.
Thermal-shutdown protection (TSD) ensures the internal drivers of IC are operating under a safe operating temperature range.
All the protection mechanisms mentioned above combine to provide a complete protecting scenario in the motor system and avoid any possible damages and guarantee under a correct and safe operation.
