A1386 from Allegro MicroSystems Europe is being applied to the market of the car in one that sensing needs flexibility and aims at at accurate time in the absolute position Can programme Huo ear effect transducer IC of line of user.

The new apparatus is unique in offering a pair of working state: Normal and low ability. Use normal way, A1386 have ratiometric output very accurate as one, can programme transducer of line of user. Use the low power way, the apparatus removes some internal spare parts and reduces the consumption. Though its accuracy is damaged at time when the low power is operated, the transducer can still be used as an area, indicatoro finds the North or the South Pole of a whirling ring magnet.

A1386 combines the circuit of the monoblock of a kind of hall component on the basis of BiCMOS, the circuit which compensates temperature learns to reduce the inherent sensitiveness drift of key element of the hall, the small signal gains the amplifier high, carry the low impedance output stage, with cancelling the circuit to study exclusively dynamically.

It is proportional to magnetic field employed that the apparatus is offered to supply the voltage output of simulation above the range in the whole 5 V. Resting voltage output and have magnetic sensitiveness is all adjustable users. The resting voltage output can be probably adjusted to 50% of the power voltage, and sensitiveness can be adjusted between 1.90 mV/G and 3.50 mV/G for the power voltage forward of 5 V.

Resting voltage and sensitiveness change to temperature extremely steady, make it drift about with the final wrong danger of output reducing to minimumly not to produce. Coefficient of temperature of sensitiveness of A1386 programme to 0.13 percent / °C factory, make apparatus those support neodymium magnet to use optimistic to have suitable users change the need.

When the power voltage forward is reduced in a certain voltage threshold, the important characteristic of one A1386 is its ability to acknowledge, apparatus 3 V on the name is operated and resting voltage output and sensitiveness are all ratiometrically climbed that time. The apparatus 5 V. on the name is very accurate

These characteristics do A1386 and is very suitable for high precision to feel in car and industry employ, because of performance of guaranteeing until - above the extended temperature range of +150°C 40°C.
