Product Description

MICROPOWER, ULTRA-SENSITIVE HALL-EF FECT SWITCHES
 
Description
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 ly 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 ing 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 fi 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 ic 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 li za tion, 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 ture range of -40°C to +85°C; range 'L' devices are rated for operation over a tem per a ture range of -40°C to +150°C. Two package styles provide a mag net i cal ly op ti - mized pack age for most ap pli ca tions. 'LH' is a min ia ture low-profile surfacemount 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.
