FD0259 Smart motor driver with embedded Hall sensor

General Description

Download

　FD0259f is a single-phase full-wave motor driver with embedded Hall-effect sensor. It integrates a H-bridge MOS driver, a high sensitivity Hall-effect sensor, an event timer for locked rotor detection, and the variable speed controlfunction with the tachometer or alarm signal output logic into the ultra-small TS826 package, which make themotors’ PCB (printed circuit board) design easier and the fabrication of small-size DC motors or FANs as simple aspossible.The external system could read the motor’s speed of rotation from FG signal of FD0259f.For safety, Lock-shutdown function turns the IC’s internal driver off to avoid over-heating when the rotor is locked,and the IC will try to re-start the motor after the shutdown interval.Thermal-shutdown protection (TSD) ensures the internal driver of IC is operating under the safe operatingtemperature range.All the protection mechanisms mentioned above combine to provide a complete protecting scenario in the motorsystem and avoid any possible damages and guarantee under a correct and safe operation.
