A3211 and A3212

Micropower, Ultrasensitive

Hall-Effect Switches

FEATURES AND BENEFITS

DESCRIPTION

• AEC-Q100 automotive qualified

• 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

TheA3211andA3212integratedcircuitsareultrasensitive,pole

independent Hall-effect switches with latched digital output.

These devices are especially suited for operation in battery-

operated, hand-held equipment such as cellular and cordless

telephones, pagers, and palmtop computers. A 2.5 to 3.5 V

operation and a unique clocking scheme reduce the average

operating power requirements to less than 15 μW with a

2.75 V supply.

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.

• Solid-state reliability

• Small size

• Easily manufacturable with magnet pole independence

PACKAGES:

DFN (EL)

Improved stability is made possible through chopper

stabilization (dynamic offset cancellation), which reduces the

residualoffsetvoltagenormallycausedbydeviceovermolding,

temperature dependencies, and thermal stress.

DFN (EH)

This device includes on a single silicon chip a Hall-voltage

generator, small-signal amplifier, chopper stabilization, a

latch, and a MOSFET output. Advanced CMOS processing

is used to take advantage of low-voltage and low-power
