OCH1501
Micro Power Unipolar Hall-effect Sensor Switch
◼ General Description
◼ Features
The OCH1501 Unipolar Hall effect sensor IC is
⚫ Micro power consumption ideal for
fabricated from mixed signal CMOS technology. It is
battery-powered applications
comprised of one Hall plate and a CMOS output driver,
⚫ Input Voltage Range: 2.2V to 4.5V
mainly designed for battery-operation, hand-held
⚫ Very High Sensitivity Hall Sensor
equipment (such as Cellular and Cordless Phone,
⚫ Chopper stabilized amplifier stage
PAD). The total power consumption in normal
⚫ Good RF noise immunity
operation is typically 28μW with a 2.8V power source.
⚫ Open Drain Output
South poles of sufficient strength will turn the output on. The output will be turned off under no magnetic field.
