General Description

Features

AH1803 is with two Hall effect plates and a CMOS output driver,

mainly designed for battery–operation, hand-held equipment

(such as Cellular and Cordless Phone, PDA). The total operation

power is down to 24uW in the 3V supply.

•

Micropower operation

Operation with North or South Pole

2.4 to 5.5V battery operation

Chopper Stabilized

• Superior temperature stability

• Extremely Low Switch-Point Drift

• Insensitive to Physical Stress

Good RF noise immunity

-40°C to 85°C operating temperature

Low profile 3 pin SC59 (commonly known as SOT23 in

Asia) and DFN2020-6 package

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 operate point

(Bop), the output will be turned on (low), the output is held until

B is lower than release point (Brp), then turned off (High).

•

ESD (HBM) ＞ 4KV for DFN2020-6

SC59 (commonly known as SOT23 in Asia) and

DFN2020-6: Available in “Green” Molding Compound

(No Br, Sb)

•

Lead Free Finish/ RoHS Compliant (Note 1)

Applications

•

Cellular phone

PDA

Cordless phone

Typical Circuit

2.4~5.5V

Output

AH1803

GND

C is for power stabilization and to strengthen the noise immunity, the

recommended capacitance is 10nF~100nF.
