FD0287fR-G1中文资料Single-Phase Driver Type- 5V AIO Motor Driver IC数据手册AAT规格书

描述 Description

\tFD0287f is a LV single-phase full-wave BLDC motor driver IC with embedded Hall-effect sensor and rotation speed(FG) output. It integrates a H-bridge MOS driver, a high and precisely sensitive Hall-effect sensor and a digital control logic with an internal clock for rotor locked driver shutdown and auto re-start, a tachometer(FG) output logic, and the BLDC motor’s speed control function in the TS826 package, it makes the BLDC motors’ PCBs(printed circuit boards) design easy and fabrication of the ultra-small BLDC motors and FANs as simple as possible. 

\tFor safety, Lock-shutdown function would turn the IC’s internal drivers off avoiding over-heat when the rotor is locked, and the IC will try to re-start the rotor’s torque after the time of these drivers’ shutdown. 

\tThe IC contains the DC bias variable speed control and the tachometer signal output function, the external succeeding system could control the BLDC motor speed and readout the BLDC motor’s speed(FG) from the signal pin of FD0287f IC.

\tThermal-shutdown protection(TSD) ensures the internal drivers of the IC are operating under a safe operating temperature range, and all the protection mechanisms mentioned above combine to provide a complete protecting scenario for the BLDC motor systems, avoid any possible damages and guarantee a correct and safe operation.
