.ORIENT-CHIP. MicroPower Ultra-Sensitive Hall-effect Switch - General Description The OCH170 Ultra-Sensitive Hall effect switch is fabricated from mixed signal CMOS technology. mainly designed for battery-operation, hand-held equipment (such as Cellular and Cordless Phone, PDA). The total power consumption in normal operation is typically 24μW with a 3V power source. Either north or south poles of sufficient strength will turn the output off. The output will be turned on under no magnetic field. While the magnetic flux density (B) is larger than operating point (BOP), the output will be turned off (high), the output is held until B is lower than release point (BRP), and then...
