A3211 and A3212

Micropower, Ultra-sensitive

Hall-effect Switches

Features and Benefits

▪ Micropower operation

▪ Operation with north or south pole

▪ 2.5 to 3.5 V battery operation

▪ Chopper stabilized

▫ Superior temperature stability

▫ Extremely low switchpoint drift

▫ Insensitive to physical stress

▪ High ESD protection

Description

The A 3211 and A3212 integrated circuits are ultra-sensitive,

pole independent Hall-effect switches with latched digital

output. These sensors are especially suited for operation in

battery-operated, hand-held equipment such as cellular and

cordless telephones, pagers, and palmtop computers. A 2.5

volt to 3.5 volt operation and a unique clocking scheme reduce

the average operating power requirements to less than 15 μW

with a 2.75 volt supply.

▪ Solid-state reliability

▪ Small size

▪ Easily manufacturable with magnet pole independence

Unlike other Hall-effect switches, either a north or south pole

of sufficient strength will turn the output on in the A3212,

and in the absence of a magnetic field, the output is off. The

A3211providesaninvertedoutput.Thepolarityindependence

and minimal power requirements allow these devices to easily

replace reed switches for superior reliability and ease of

manufacturing, while eliminating the requirement for signal

conditioning.

Packages:

Improved stability is made possible through chopper

stabilization (dynamic offset cancellation), which reduces the

residualoffsetvoltagenormallycausedbydeviceovermolding,

temperature dependencies, and thermal stress.
