AH1822
MICROPOWER OMNIPOLAR HALL-EFFECT SENSOR
SWITCH
General Description
Features
AH1822 is comprised of two Hall effect plates and an open-drain
•
•
Micropower operation
Operation with magnetic field of either north or south
pole (omnipolar)
2.5V to 5.5V battery operation
Chopper stabilized
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.
•
•
• Superior temperature stability
• Extremely Low Switch-Point Drift
• Insensitive to Physical Stress
Good RF noise immunity
-40°C to 85°C operating temperature
ESD (HBM) ＞ 5KV
Either north or south pole of sufficient strength will turn the output
on. The output will be turned off under no magnetic field. While
the magnetic flux density (B) is larger than operating point (Bop),
the output will be turned on (low), the output is held until B is
lower than release point (Brp), then turned off.
•
•
•
•
DFN2015-6 and DFN3020-6: Available in “Green”
Molding Compound (No Br, Sb)
•
Lead Free Finish/ RoHS Compliant (Note 1)
Applications
•
•
•
Cover switch in clam-shell cellular phones
Cover switch in Notebook PC/PDA
Contact-less switch in consumer products

Notes:
5. When power is initially on, the operating Vdd (2.5V to 5.5V) must be applied to be guaranteed for the output sampling. The output state is valid
after the second operating phase (typical 150ms).
