A1210、A1211、A1212、A1213和A1214：连续时间闩锁系列

The Allegro A1210-A1214 Hall-effect latches are next generation replacements for the popular Allegro 317x and 318x lines of latching switches. The A121x family, produced with BiCMOS technology, consists of devices that feature fast power-on time and low-noise operation. Device programming is performed after packaging, to ensure increased switchpoint accuracy by eliminating offsets that can be induced by package stress. Unique Hall element geometries and low-offset amplifiers help to minimize noise and to reduce the residual offset voltage normally caused by device overmolding, temperature excursions, and thermal stress.

The A1210-A1214 Hall-effect latches include the following on a single silicon chip: voltage regulator, Hall-voltage generator, small-signal amplifier, 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.

BiCMOS工艺的小几何结构允许这些器件以超小型封装形式提供。可用的封装样式为大多数应用提供磁优化的解决方案。封装LH是一个SOT23W，一个微型低剖面表面贴装封装，而封装UA是一个三引线超小型SIP通孔安装。每个包装是无铅（铅），与100%亚光镀锡引线框架。亚博尊贵会员
