The iST8508 Hall effect sensor IC is fabricated with mixed signal CMOS technology. It comprises one AMR sensor, one Hall plate, and a CMOS output driver, mainly designed for battery-operation, hand-held equipment (such as Cellular and Cordless Phone, PAD). The total power consumption in normal operation is typically 18.81μW with a 3.3V power source.
Applications:
Cover switch in clam-shell cellular phones
Cover switch in Notebook PC/PAD
Contact-less switch in consumer products
Solid State Switch
Handheld Wireless Handset Awake Switch
Lid close sensor for battery-powered devise
Magnet proximity sensor for reed switch replacement
Features:
- Micro power consumption ideal for battery-powered applications
- Omni-polar (operation with magnetic field of either north or south pole), easy to use as output
- Input Voltage Range: 2.5V to 5.5V
- Very high sensitivity hall sensor
- Chopper stabilized amplifier stage
- Good RF noise immunity
- SOT23-3L package
- No need of a pull-high resistor
