Features
AH1801
MICROPOWER, ULTRA-SENSITIVE HALL EFFECT
SWITCH
General Description
• Micropower operation
• Operation with North or South Pole
• 2.5V to 5.5V battery operation
• Inverted Output-on without Magnet present
• 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 DFN2020-3, DFN2020-6 package
• ESD (HBM) > 5KV for DFN2020-3 and DFN2020-6
> 6KV for SC59
• SC59, DFN2020-3 and DFN2020-6: Available in
“Green” Molding Compound (No Br, Sb)
• Lead Free Finish / RoHS Compliant (Note 1)
AH1801 is a Micropower, Ultra-sensitive Hall Effect Switch, which
is with two Hall effect plates and a 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.
Either north or south pole of sufficient strength will turn the output
off. The output will be turned on under no magnetic field.
While the magnetic flux density (B) is larger than operate point
(Bop), the output will be turned off, the output is held until B is
lower than release point (Brp), then turned on.
Applications
• Cellular phone
• PDA
• Cordless phone
