OCH168B

WW W 1. 2O 3RIENT-CHIP.COM OCH168B Micro Power Omnipolar Hall-effect Sensor Switch ◼ General Description The OCH168B Omnipolar Hall effect sensor IC is fabricated from mixed signal CMOS technology. It is comprised of two Hall plates and a OD output driver, 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 on. The output will be turned off under no magnetic field. While the magnetic flux density (B) is larger than operating point (BOP), the output will be turned on (low), the output is held until B is lower than release point (BRP), and then turned off. The OCH168B is available in many flexible packaging options, such as SIP-3L, TSOT23-3L. Operating temperature range of the OCH168B is from -40°C to 85°C. To minimize the BOM cost, capacitors of the MLCC type are support...
