MICROPOWER, ULTRA-SENSITIVE
HALL-EFFECT SWITCHES
The A3213xx and A3214xx integrated circuits are ultra-sensitive, pole
independent Hall-effect switches with a latched digital output. They are
especially suited for operation in battery-operated, hand-held equipment such
as cellular and cordless telephones, pagers, and palmtop computers. A 2.4 volt
to 5.5 volt operation and a unique clocking scheme reduce the average oper-
ating power requirements 鈥?the A3213xx to 825 碌W, the A3214xx to 14 碌W
(typical at 2.75 V)! Except for operating duty cycle and average operating
current, the A3213xx and A3214xx are identical.
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 allows
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 (dy-
namic offset cancellation), which reduces the residual offset voltage normally
caused by device overmolding, temperature dependencies, and thermal stress.
These devices include 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.
Range 'E' devices are rated for operation over a temperature range of
-40擄C to +85擄C; range 'L' devices are rated for operation over a temperature
range of -40擄C to +150擄C. Two package styles provide a magnetically opti-
mized package for most applications. 鈥楲H鈥?is a miniature low-profile surface-
mount package, 鈥楿A鈥?is a three-lead SIP for through-hole mounting. Each
package is available in a lead (Pb) free version (suffix,
鈥揟)
, with a 100% matte
tin plated leadframe.

ceptible to damage if exposed to extremely
high static electrical charges.
