MICROPOWER, ULTRA-SENSITIVE

HALL-EFFECT SWITCH

Preliminary Information

(Subject to change without notice)

November 12, 2001

The A3212 integrated circuit is an ultra-sensitive, pole independent Hall-

effect switch with a latched digital output. This sensor is 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

Package Suffix ‘LH’ Pinning

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.

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

strength will turn the output on; in the absence of a magnetic field, the output is

off. The polarity independence and minimal power requirement allow these

devices to easily replace reed switches for superior reliability and ease of

manufacturing, while eliminating the requirement for signal conditioning.

Improved stability is made possible through chopper stabilization (dynamic

offset cancellation), which reduces the residual offset voltage normally caused

by device overmolding, temperature dependencies, and thermal stress.

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

small-signal amplifier, chopper stabilization, a latch, and a MOSFET output.

Advanced BiCMOS processing is used to take advantage of low-voltage and

low-power requirements, component matching, very low input-offset errors,

and small component geometries.

The A3212Ex is rated for operation over a temperature range of -40°C to

85°C. The A3212Lx is rated for operation over a temperature range of -40°C to

150°C. Two package styles provide a magnetically optimized package for most

applications. Suffix ‘LH’ is a miniature low-profile surface-mount package

while suffix ‘UA’ is a three-lead ultra-mini-SIP for through-hole or surface

mounting.

Caution: These CMOS devices have input

static protection (Class 3) but are still

susceptible to damage if exposed to

extremely high static electrical charges.

Always order by complete part number: the prefix ‘A’ + the basic four-digit

part number + the suffix ‘E’ or ‘L’ to indicate operating temperature range + a

suffix to indicate package style, e.g., A3212ELH .
