FD0252fR-G1数据手册AAT中文资料规格书

描述 Description

\tFD0252f is a LV 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, motors’ status(RD) signal output logic only in a TS825 package, which make the motors’ PCBs(printed circuit boards) design easy and fabricate the small and tiny size DC motors or FANs as simply as possible. 

\tFor 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. 

\tFD0252f is built-in the alarm signal output function, the external system could be readout the motor’s status(RD) from the signal pin of FD0252f IC.

\tThermal-shutdown protection(TSD) ensures the internal drivers of IC are operating under a safe operating temperature range. 

\tAll 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.
