Introduction

AI Translation

The SD211VB is an IC with a built-in Hall sensor and tachometer function, designed for electronic commutation of BLDC motors or fans. The device integrates an internal voltage regulator, Hall sensor, Hall voltage amplifier, Schmitt trigger, and two complementary open-collector output stages. When the south pole magnetic field strength perpendicular to the Hall element exceeds the operate point threshold B_OP, output DO switches low (ON) and output DOB&FG switches high (OFF). When the magnetic field strength drops below the release point B_RP, output DO switches high (OFF) and output DOB&FG switches low (ON). The difference between the operate point and release point is the device's magnetic hysteresis B_HYS; this built-in hysteresis ensures accurate output switching even in the presence of external mechanical vibration and electrical noise. The device is available in a TO-94 package.
