Description

SI-6633C is a 3-phase brushless DC motor pre-driver.
This device can be used together with wide variety of Nchannel MOSFETS, supporting motor power voltages up to 30V.
Phase is switched by hall elements arranged at an interval of 120°.
Built-in functions include PWM current control for limiting inrush current, thermal shutdown, and synchronous rectification.
The synchronous rectification fnction rectifies by MOSFET of low temperature resistance in place of a body diode, thus reducing power loss at the time of regeneration.
This product offers enable, direction, brake inputs that can control electric current by internal PWM.
Also, rotation of the motor can be detected by logc output FG.
