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
