9 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

9.1 Application Information

The DRV5053 device is used in magnetic-field sensing applications.

9.2 Typical Applications

9.2.1 Typical Application With No Filter

Figure 12. Typical Application Schematic – No Filter

9.2.1.1 Design Requirements

For this design example, use the parameters listed in Table 1 as the input parameters.

System bandwidth

15 kHz

9.2.1.2 Detailed Design Procedure

The DRV5053 has internal filtering that limits the bandwidth to at least 20 kHz. For this application no external

components are required other than the C1 bypass capacitor, which is 0.01 µF minimum. If the analog output

OUT is tied to a microcontroller ADC input, the equivalent load must be R > 10 k

Ω and C < 10 nF.
