AH1801
MICROPOWER OMNIPOLAR, ULTRA-SENSITIVE HALL
EFFECT SWITCH
General Description
Features
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
•
•
•
•
•
Micropower operation
Operation with North or South Pole
2.5V to 5.5V battery operation
Inverted Output-on without Magnet present
Chopper stabilized
24uW in the 3V supply.
•
Superior temperature stability
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.
•
•
•
•
•
•
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 and DFN2020-6 package
ESD (HBM) ＞ 5KV for DFN2020-6
＞ 6KV for SC59-3L
•
•
Lead Free Finish / RoHS Compliant
SC59 and DFN2020-6: Available in “Green” Molding
Compound (No Br, Sb)
Applications
