A1101, A1102, A1103, A1104, and A1106  
Continuous-Time Switch Family  
The Allegro® A1101-A1104 and A1106 Hall-effect switches are next generation  
replacements for the popular Allegro 312x and 314x lines of bipolar switches.  
The A110x family, produced with BiCMOS technology, consists of devices that  
feature fast power-on time and low-noise operation. Device programming is per-  
formed after packaging, to ensure increased switchpoint accuracy by eliminating  
Package LH, 3-pin Surface Mount  
offsets that can be induced by package stress. Unique Hall element geometries and  
3
low-offset amplifiers help to minimize noise and to reduce the residual offset volt-  
age normally caused by device overmolding, temperature excursions, and thermal  
stress.

The A1101-A1104 and A1106 Hall-effect switches include the following on a  
single silicon chip: voltage regulator, Hall-voltage generator, small-signal ampli-  
fier, Schmitt trigger, and NMOS output transistor. The integrated voltage regulator  
permits operation from 3.8 to 24 V. The extensive on-board protection circuitry  
makes possible a ±30 V absolute maximum voltage rating for superior protection  
in automotive and industrial motor commutation applications, without adding  
external components. All devices in the family are identical except for magnetic  
switchpoint levels.

The small geometries of the BiCMOS process allow these devices to be pro-  
vided in ultrasmall packages. The package styles available provide magnetically  
optimized solutions for most applications. Package LH is an SOT23W, a miniature  
low-profile surface-mount package, while package UA is a three-lead ultramini  
SIP for through-hole mounting. Each package is lead (Pb) free, with 100% matte  
tin plated leadframes.
