ULTRA-SENSITIVE BIPOLAR

HALL-EFFECT SWITCHES

These Hall-effect switches are designed for magnetic actuation using

a bipolar magnetic field, i.e., a north-south alternating field. They

combine extreme magnetic sensitivity with excellent stability over

varying temperature and supply voltage. The high sensitivity permits

their use with multi-pole ring magnets over relatively large distances.

Each device includes a voltage regulator, quadratic Hall voltage

generator, temperature stability circuit, signal amplifier, Schmitt trigger,

and open-collector output on a single silicon chip. The on-board regula-

tor permits operation with supply voltages of 4.5 to 24 V. The switch

output can sink up to 25 mA. With suitable output pull up, they can be

used directly with bipolar or MOS logic circuits.

The three package styles available provide a magnetically optimized

package for most applications. Suffix ‘LT’ is a miniature SOT-89/TO-

243AA transistor package for surface-mount applications; suffixes ‘U’,

and ‘UA’ feature wire leads for through-hole mounting. Prefix ‘UGN’

devices are rated for continuous operation over the temperature range of

-20°C to +85°C, prefix ‘UGS’ devices over an extended range of -40°C

to +125°C, and prefix ‘UGL’ devices over the range of -40°C to +150°C.
