A1180 – A1184

Preliminary Data Sheet

Two-Wire, Programmable, Chopper-Stabilized,

Unipolar Hall-Effect Switch

PRELIMINARY DATA SHEET

SUBJECT TO CHANGE WITHOUT NOTICE

The A118X is a two-wire, unipolar, Hall-effect switch family designed

for use in high-temperature applications. This device uses a patented high

frequency chopper-stabilization technique on Allegro's new DABIC5

BiCMOS wafer fabrication process to achieve magnetic stability and to

eliminate offset inherent in single-element devices and from harsh-

application environments.

The A118X FAMILY of devices incorporates a programmability

function to allow for external trimming of the operate point.

The

programming is performed after final packaging of the sensor and

placement of the Single In-Line Package (SIP) into the application. This

advanced feature allows for optimization of sensor switching performance

by effectively accounting for variations caused by magnet and SIP

placement tolerances.

These devices provide on-chip transient protection. A zener clamp on

the power supply protects against over-voltage conditions on the supply

line.

The output of the A118X FAMILY, with the exception of the A1180/2,

will switch HIGH in the presence of a sufficiently large south-pole magnetic

field and will switch LOW with the removal of the field. The A1180/2 has

the opposite polarity as the others, switching LOW in the presence of a

sufficient magnetic field and HIGH with the removal of the field.

Two package styles provide a magnetically optimized package for

most applications. Suffix “LH” is a miniature low profile package for

surface-mount applications; suffix “UA” is a three-lead ultra-mini Single

Inline Package (SIP) for through-hole mounting.

Factory programmed versions also available, see A1140/42/43/45.

Programming software and/or hardware demonstration kits also available

see ASEK-01 on the Allegro web site, www.allegromicro.com.

See typical application drawing for UA pinning.
