OCH167/OCH167A
Micro Power Omnipolar Hall-effect Sensor Switch
◼ General Description
◼ Features
The OCH167 Omnipolar Hall effect sensor IC is
⚫ Micro power consumption ideal for
fabricated from mixed signal CMOS technology. It is
battery-powered applications
comprised of two Hall plates and a CMOS output
⚫ Omnipolar (operation with magnetic field of either
driver, mainly designed for battery-operation,
north or south pole), easy to use as output
hand-held equipment (such as Cellular and Cordless
switches with both North and South pole
Phone, PDA). The total power consumption in normal
⚫ Input Voltage Range: 2.2V to 3.65V
operation is typically 39μW with a 3V power source.
