Allegro announces a new field-programmable, unipolar Hall-effect change designed for use in high-temperature software. The A1128 device works on the chopper-stabilization technique to eliminate balanced out inherent in single-element devices. Allegro’s new device has an superior programming algorithm to simplify the client’s end-of-line process. It also has a higher programming solution for tighter magnet switch points. It really is targeted at the car and industrial markets.

The devices are outside the body programmable. A wide range of programmability is available on the magnetic function point, BOP, while the hysteresis is still fixed. This advanced feature allows optimisation of the sensor IC switchpoint and can drastically counteract mechanical placement tolerances found in end-use production conditions. A proprietary vibrant offset cancellation method, with an internal high-frequency clock, reduces the residual balance out voltage, which is usually caused by device overmolding, temperature dependencies, and thermal tension. Having the Hall aspect and amplifier in a single chip minimizes numerous problems normally connected with low-level analog signals.

This device is offered in the UA package. The UA is a three-lead ultra-mini SIP for through-hole mounting. This package is lead (Pb) free, with 100% flat tin plated leadframes. The A1128LUA-T is priced at $0.49 throughout quantities of 1,000.
