Bipolar Switches are offered in 2 packaging options.
Press Release Summary:
Available in 3-pin single in-line package (UA) and 3-pin SMT package (LH), A1201/02/03/04 Hall-effect switches offer Pb-free plating option and are stress-resistant for use in extended temperature ranges. Hall plate geometries and low-offset low-noise amplifiers minimize noise and reduce residual offset voltage. Produced in BiCMOS technology, products are suited for computer/office, industrial, and automotive markets.Original Press Release:
Allegro Microsystems, Inc. Replaces Bipolar Switch Family for Improved Performance and Additional Packaging Options
Worcester, MA, June 20, 2005 - Allegro MicroSystems, Inc. introduces the A120x family, which is intended not only to replace our legacy A3132/3/4 family of bipolar switches with improved performance, but also to offer our customers a wider variety of packaging options. Additionally, for the first time, Allegro is offering a Pb-free plating option for with our bipolar switch family to comply with various international standards.
The Allegro A1201/02/03/04 Hall-effect bipolar switches are stress-resistant sensors suited for operation over extended temperature ranges. These devices are drop-in replacements for the popular Allegro A3132, A3133 and A3134 line of sensors. This family produced in BiCMOS technology features fast power-on time and low noise operation. The high performance is made possible through unique Hall plate geometries and low offset low noise amplifiers that minimize noise and reduce the residual offset voltage normally caused by device over-molding, temperature dependencies and thermal stress. The device's magnetic switchpoints are optimized at test with end-of-line trimming, which provides tighter switchpoint ranges than the A313X line of bipolar switches. All devices in the family are identical except for magnetic switchpoints.
New packaging selections for this product line offer customers more options in design, while an extended temperature range is available for automotive and industrial markets. Targeted to the consumer, computer/office, industrial and automotive markets, the A120x family is provided in a three-pin single in-line package (UA) and a three-pin surface-mount package (LH). The A120x is priced at $0.41 at quantities of 10,000 for the 'E' temperature range. The leadtime for both packages is 6-8 weeks.
Allegro MicroSystems, Inc. is a supplier of advanced mixed-signal power semiconductors and Hall-effect sensors targeted toward the automotive, communications, computer/office automation, consumer and industrial markets. It maintains a leadership position in the integrated magnetic sensor and integrated motor driver product segments. With over 2,000 employees, Allegro is headquartered in Worcester, MA.
