Description
A1101EUA-T Allegro Micro Systems Hall Effect Sensor 25mA Unipolar 5V/9V/12V/15V/18V 175G, 20 mA, 3-SIP, Hall Effect Type:Switch, Operate Point Typ:100G, Release Point Typ:45G, Supply Voltage Min:3.8V, Supply Voltage Max:24V, Sensor Case Style:SIP, 3-Pin Ultra Mini SIP Bulk
The Allegro A1101/2/3/4 and A1106 Hall-effect switches are produced with BiCMOS technology enabling fast power-on time and low-noise operation. Device programming is performed after packaging, to ensure increased switch-point accuracy by eliminating offsets that could be induced by package stress.
Unique Hall element geometries and low offset amplifiers minimise noise and to reduce the residual offset voltage normally caused by device over-molding and thermal stress.
The Allegro A1101/2/3/4 and A1106 a voltage regulator, Hall voltage generator, small-signal amplifier, Schmitt trigger, and NMOS output transistor.
