01.This Hall-effect switch is monolithic integrated circuits with tighter magnetic specifications, designed to operate continuously over extended temperatures to +150°, and is more stable with both temperature and supply voltage changes. The negative compensation slope is optimized to match the negative temperature coefficient of low cost magnets.
02.Band gap regulation provides extremely stable operation over 3.8 to 30 VDC supply voltage range. BL-HE-ST8505 hall sensor is capable of continuous 20 mA sinking output, and may be cycled as high as 50 mA maximum.
