The A3213xx and A3214xx integrated circuits are ultra-sensitive, pole
in de pen dent Hall-effect switches with a latched digital output. They are
es pe cial y suited for operation in battery-operated, hand-held equip ment such
as cellular and cordless tele phones, pagers, and palmtop com put ers. A 2.4 volt
to 5.5 volt operation and a unique clocking scheme reduce the average op er
at ng power requirements – the A3213xx to 825 μW, the A3214xx to 14 μW
(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 suf i cient
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-
nam c offset cancellation), which reduces the residual offset voltage normally
caused by device overmolding, temperature de pen den cies, and thermal stress.
These devices include on a single silicon chip a Hall-voltage generator,
small-signal amplifier, chopper sta bi i za ion, 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 tem per a ure range of
-40°C to +85°C; range 'L' devices are rated for operation over a tem per a ure
range of -40°C to +150°C. Two package styles provide a mag net cal y op i
mized pack age for most ap pli ca ions. ‘LH’ is a min a ure low-profile surface-
mount package, ‘UA’ is a three-lead SIP for through-hole mounting. Each
package is available in a lead (Pb) free version (suffix,
–T
) , with a 100% matte
tin plated leadframe.
