... VCC 0.01 μF A1190-DS, Rev. 3 A1190, A1192 and A1193 Description The A1190, A1192, and A1193 comprise a family of two- wire, unipolar, Hall-effect switches, which can be trimmed by the user at end-of-line to optimize magnetic switchpoint accuracy in the application. These devices are produced on the Allegro ® ...

Typical application circuits Chopper Stabilization Technique When using Hall-effect technology, a limiting factor for switchpoint accuracy is the small signal voltage developed across the Hall element. This voltage is disproportionally small relative to the offset that can be produced at the output of the Hall sensor IC ...

... A1190, A1192, and A1193 Overview Programming is accomplished by sending a series of input volt- age pulses serially through the VCC (supply) pin of the device. A unique combination of different voltage level pulses controls the internal programming logic of the device to select a desired programmable parameter and change its value. There are three voltage levels that must be taken into account when program- ming ...

... A1190, A1192, and A1193 Code. The number used to identify the combination of fuses activated in a bit field, expressed as the decimal equivalent of the binary value. The LSB of a bit field is denoted as code 1, or bit 0. Addressing. Setting the bit field code in a selected register by serially applying a pulse train through the VCC pin of the device ...

... A1190, A1192, and A1193 Try Mode In Try mode, bit field addressing is accomplished by applying a series of V pulses to the VCC pin of the device shown in figure 6. Each pulse increases the bit field value for the selected parameter, increasing by one on the falling edge of each additional V pulse ...

... A1190, A1192, and A1193 To correctly address the fuses to be blown, the code represent- ing the required parameter value must be translated into a binary number. For example, as shown in figure 7, decimal code 5 is equivalent to the binary number 101. Therefore bit 2 must be addressed and blown, the device power supply cycled, and then bit 0 must be addressed and blown ...

... A1190, A1192, and A1193 The device must be operated below the maximum junction tem- perature of the device, T (max). Under certain combinations of J peak conditions, reliable operation may require derating supplied power or improving the heat dissipation properties of the appli- cation. This section presents a procedure for correlating factors affecting operating T ...
