Sensitive Two-Wire Field-Programmable Chopper-Stabilized Unipolar Hall-Effect Switches

A1182, and A1183

Sensitive Two-Wire Field-Programmable

Chopper-Stabilized Unipolar Hall Effect Switches

Description (continued)

switches. Additionally, the system designer gains inherent diagnos-

tics because output current normally flows in either of two nar-

rowly-specified ranges. Any output current level outside of these

two ranges is a fault condition. The A1180-83 family of devices

also features on-chip transient protection, and a Zener clamp to

protect against overvoltage conditions on the supply line.

The output currents of the A1181 and A1183 switch HIGH in the

presence of a south polarity magnetic field of sufficient strength;

and switch LOW otherwise, including when there is no significant

magnetic field present. The A1180 and A1182 have inverted out-

put current levels: switching LOW in the presence of a south polar-

ity magnetic field of sufficient strength, and HIGH otherwise. The

devices also differ in their specified LOW current supply levels.

Both devices are offered in two package styles: LH, a SOT-23W

miniature low-profile package for surface-mount applications,

and UA, a three-lead ultramini Single Inline Package (SIP) for

through-hole mounting. Each package is available in a lead (Pb)

free version (suffix, –T) with 100% matte tin plated leadframe.

Factory-programmed versions are also available. Refer to: A1140,

A1141, A1142, A1143, A1145, and A1146.

1Pb-based variants are being phased out of the product line.

a. Certain variants cited in this footnote are in production but have been determined to be LAST TIME BUY. This classification indicates that sale of this device is cur-

rently restricted to existing customer applications. The device should not be purchased for new design applications because obsolescence in the near future is probable.

Samples are no longer available. Status change: October 31, 2006. Deadline for receipt of LAST TIME BUY ORDERS: April 27, 2007. These variants include: A1180EUA,

A1180LLHLT, A1180LUA, A1182ELHLT, A1182EUA, A1182LUA, A1183EUA, and A1183LLHLT.

b. Certain variants cited in this footnote are in production but have been determined to be NOT FOR NEW DESIGN. This classification indicates that sale of this device is

currently restricted to existing customer applications. The device should not be purchased for new design applications because obsolescence in the near future is probable.

Samples are no longer available. Status change: May 1, 2006. These variants include: A1180ELHLT, A1181ELHLT, A1181EUA, A1181LLHLT, A1181LUA , A1182LLHLT,

A1183ELHLT, and A1183LUA.
