Features

AH1885

MICROPOWER, ULTRA-SENSITIVE HALL EFFECT

SWITCH

General Description

• Micropower operation

• Operation with North or South Pole

• 1.65 to 3.3V 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

• ESD ＞ 4KV in human body mode

• SOT553: Available in “Green” Molding Compound

(No Br, Sb)

• Lead Free Finish/RoHS Compliant (Note 1)

AH1885 is with two Hall effect plates and dual CMOS output

driver, mainly designed for battery–powered, hand-held

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

total operation power is down to 15uW in the 1.8V supply.

Either north or south pole of sufficient strength will turn the

output1 on. The output1 will be turned off under no magnetic

field.

While the magnetic flux density (B) is larger than operate point

(Bop), the output1 will be turned on (low), the output1 is held until

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

Applications

• Cellular phone

• PDA

• Cordless phone
