MICROPOWER, 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
24uW in the 3V supply.

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
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.

Notes:
5. When power is initially on, the operating Vdd (2.5V to 5.5V) must be applied to be guaranteed for the output sampling. The output state is
valid after the second operating phase (typical 150ms).
