Description

The Allegro® A1201, A1202, A1203, and A1204 Hall-effect bipolar switches are next-generation replacements and extension of the popular Allegro A3134, A3133, and A3132 bipolar switch product line. Overall, the A120x family, produced with BiCMOS technology, consists of continuous-time 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 lowoffset amplifiers help to minimize noise and to reduce the residual offset voltage normally caused by device overmolding, temperature excursions, and thermal stress. The A120x Hall-effect bipolar switches 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 motor commutation Packages: 3 pin SOT23W (suffix LH), and 3 pin SIP (suffix UA) Continued on the next page Not to scale Functional Block Diagram VCC Regulator To all subcircuits VOUT Amp Gain Offset Trim Control GND A1201-DS, Rev. 5 A1201, A1202, A1203, and A1204 Continuous-Time Bipolar Switch Family provide magnetically optimized solutions for most applications.
