BLDC motor drivers and controllers

STL6300

The STL6300 is a three-phase BLDC motor Driver SiP with core 1T-8052, 16Kx8 embedded Flash, integrates 5V LDO power management and built-in 6N-MOS driver. In addition, it also has a comparator for sensorless detection of motor commutation and a smart fan communication interface. It can provide a driving current of up to 6.5A and operates reliably within a working voltage range of 6V to 20V. The STL6300 offers advanced closed-loop control within ±5% variation of rotation speed and soft-start feature with programmable incremental duty cycle to smooth-out the power-up spike on the coil current which can reduce the start-up noise and relax the power budge. In addition, it provides a current limiting function by internal reference voltages. The device supports lock detection and cease the output current automatically. Once the external load is relaxed, it will automatically recover to system-specified speed. Various open-drain output types, such as FG, RD, Stop RD, and Reverse RD, are implemented as the tachometer for system to monitor the speed of a DC fan with 4, 6, or 8 magnetic poles.
