Hi
I got DRV 5053 Hall effect Bipolar analog output magnetic sensor.
I want to know what is the Minimum and maximum gauss value of sensing...??

Yuva,
First determine what sensitivity variant of the device you have. For example, the EA variant (DRV5053EA) has a typical sensitivity (S) of 45 mV/mT.
Also note, that the output voltage will not exceed 1.8V or go below 0.2V. Also, at 0-Tesla, the output voltage is 1.02V (VQ) typically. Since the output is linear you can determine the typical minimum and maximum gauss values with following equations:
Max gauss sense = (1.8V - 1.02V)/S = 17.33 mT
Minimum guass sense = (0.2V - 1.02V)/S = -18.22 mT
Please read through datahseet for more information.
Also note, that the calculations above are with typical values. The sensitivity (S) for EA variant can at a maximum be 70mV/mT. You will need to design for this worst case, or calibrate/measure the sensitivity of your device. The quiescent output (VQ) can also vary slightly.
