OCH166A
Micro Power Omnipolar Hall-effect Sensor Switch
◼ General Description
◼ Features
The OCH166A omnipolar Hall effect sensor IC is ⚫ Micro power consumption ideal for battery-powered
fabricated from mixed signal CMOS technology. It is
applications
comprised of one Hall plate and a CMOS output driver, ⚫ Omnipolar (operation with magnetic field of either
mainly designed for battery-operation, hand-held
north or south pole), easy to use as output
equipment (such as Cellular and Cordless Phone, ⚫ Input Voltage Range: 1.65V to 3.6V
PAD). The total power consumption in normal ⚫ Very High Sensitivity Hall Sensor
operation is typically 4μW with a 1.8V power source. ⚫ Chopper stabilized amplifier stage
South poles of sufficient strength will turn the output
on.
