OCH177 Micro Power Omnipolar Hall-effect Sensor Switch

The OCH177 Omnipolar Hall-effect Sensor IC is fabricated from mixed signal CMOS technology. It is comprised of two Hall plates and a CMOS 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 o.
