Hi David,
Are they referring to the DRV5055 or the automotive qualified DRV5055-Q1? We have some of this info for the DRV5055-Q1 at the below link:

Part Number: DRV5057 Other Parts Discussed in Thread: , DRV5055-Q1 Hi team,
The customer uses DRV5057 as the sensor chip of the brake foot valve. Foot valve is required to output 2 complementary PWM signals. Customer would like to know If he uses two…
Martijn, in response to your first post, please check out the DRV5055-Q1. The "A1" version has a ±21 mT range. Initial lifetime data shows Sensitivity drift to be <0.5%.
Best regards,

Erwin,
Those specific answers, I don't have - I can say that TI has parts that go in commercial applications like consumer electronics to automotive applications and on up to satellites in space.
Perhaps you were thinking you just wanted a mechanical…
Hello Yulei,
Your description of the test procedure is not clear to me.How exactly did you excite the sensors? Did you use a time-varying current or a moving permanent magnet to generate the input flux signal? Did you apply the same excitation to both…
One option I can readily think of is to use two of the DRV5055-Q1 placed 90° from each other around a rotating magnet, like this quick illustration I've done here:
And if you call those sensors X and Y, then you can get voltages relative to the magnetic…
Hello Cailyn,
The range in sensitivity is simply a correlation to products on reception. DRV5053 is really not a precision device regardless of temperature. If tighter sensitivity ranges are needed, I would recommend using the DRV5055-Q1. The device…
