DESCRIPTION
The A3213 and A3214 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 cell and cordless
telephones and palmtop computers. A 2.4 to 5.5 V operation
and a unique clocking scheme reduce the average operating
power requirements: the A3213 to 825 µW, the A3214 to
14 µW (typical, at 2.75 V). Except for operating duty cycle
and average operating current, the A3213 and A3214 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 reliabil-
ity and ease of manufacturing, while eliminating the require-
ment for signal conditioning.
Improved stability is made possible through chopper sta-
bilization (dynamic offset cancellation), which reduces the
residual offset voltage normally caused by device overmold-
ing, temperature dependencies, and thermal stress.
