Step 1. Insert the USB cable into the EVM onboard USB receptacle. Step 2. For proper calibration, make certain that there are no magnets within a few feet of the EVM when the EVM powers up. Step 3. Plug the USB cable into any USB power adapter (for example, laptop, desktop, power bank, and so on). LED D13 on the far bottom right of the board indicates the board is powered, calibrated, and is taking sample measurements from the DRV5055A1 (default EVM startup device). 2.2 Measurements The DRV5055EVM measures a magnetic field with multiple devices and the respective gain variants. Push-button S1 selects the different gain variants of the DRV5055 devices. The devices are arranged such that gain variants increase sequentially from right to left. The LCD displays the measurement corresponding to the selected device. The measurement format is adjusted by the slide switch labeled Display Mode (K1). Step 1. Click the Device Select Switch until an LED indicates the device of interest is selected. Step 2. Adjust the Display Mode slide switch to the measurement format of interest. Step 3. Introduce magnetic stimulus (for example, the magnet included in the evaluation kit). 4 DRV5055EVM SLYU047A – April 2018 – Revised May 2018 Submit Documentation Feedback Copyright © 2018, Texas Instruments Incorporated Hardware www.ti.com 3 Hardware The DRV5055 is a linear Hall effect magnetic-sense solution that provides ease of use and high performance. The DRV5055EVM is intended to provide basic functional evaluation of this device family. The fixture layout is not intended to be a model for the target circuit, nor is it laid out for electromagnetic compatibility (EMC) testing. The DRV5055EVM consists of one PCB with each of the gain variants of the DRV5055. The EVM kit also provides a USB cable for quick power-up, as well as a magnet for quick qualitative assessment of the DRV5055 variants performance. 3.1 Features The layout of the DRV5055EVM printed circuit board (PCB) is designed to provide the following features: • Evaluation of all gain options for the DRV5055 • Easily access device pins through test points • Easily read voltage, mT, and microcontroller ADC memory values from the onboard LCD • Toggle between devices with a press of the Device Select Switch, push-button S1. See the links in Table 3 for comprehensive information about the DRV5055 family of devices. 3.2 Theory of Operation The DRV5055EVM is a plug and play board, requiring only that the user supply power and provide a magnetic stimulus after the initial calibration. The ease of operation can be attributed to the onboard microcontroller. The source code for the microcontroller is available on the DRV5055 web folder under Tools and Software. The basic operation of the microcontroller source code is outlined in the state machine diagram shown in Figure 1. Upon receiving power, the microcontroller registers are set up to properly interact with the other devices on the board. Then, a preliminary measurement of each DRV5055 gain variant is taken. It is imperative that the magnetic stimulus of interest is not present at this time, as this measurement sets the 0 point in the mT measurement display. After calibration is complete, the LED for the DRV5055A1 powers on by default. At this point, the EVM microcontroller begins continuously sampling the DRV5055A1. Pressing push-button S1 results in the EVM sampling the next adjacent device. After every 32 samples are taken, the device calculates an average, and processes the data to fit the format selected by the slider switch K1.

C1, R1, and R2 are the additional passives required for the emulation tool to effectively communicate with the MSP430FR4133 for the purposes of programming and debugging. The MSPFETFlash can be obtained separately at http://www.ti.com/tool/MSP-FET. Alternatively, if an MSP430FR4133 Launchpad is already available, that board can be configured to program the DRV5055EVM microcontroller. 3.3.2 C2-C5, C29, C32, C36, C43 C2-C5 are the 1-µF supply bypass capacitors for the DRV5055. C29, C32, C36, and C43 are the supply bypass capacitors for the MSP430FR4133, SN74LVC1G17, LP5907MFX-3.3, TCA9535, and TS5A23159, respectively. 3.3.3 C8--C11, R3-R6 These components are used to form low-pass filters on the outputs of all of the DRV5055Ay devices, where y = 1 to 4. The capacitors also allow the ADC input node to remain relatively stable throughout the ADC sample transition. 3.3.4 J2 J2 is the male USB connector that allows the device to be powered through a PC USB port or USB adapter. 3.3.5 K1, R47, R48, R49 K1 serves as a slide switch that pulls GPIO extender TCA9535 GPIO pins P00, P01, and P02 either to GND or to 3.3-V VCC through pullup resistors R47, R48, and R49. 3.3.6 R16 and S1 R16 is a pullup resistor that ties push-button switch S1 to the 3.3-V VCC when S1 is not pushed. 3.3.7 C55, R51, and U14 C55 and R51 form a low-pass filter with the push-button stimulus, and are used with SN74LVC1G17 Schmitt Trigger (U14) to mitigate the effects of debounce from the push-button. 3.3.8 U9-U12 U9-U12 Correspond to each of the gain variants of the DRV5055 device. The gains are arranged highest to lowest with U9 being the A4 variant while U12 is the A1 variant. 3.3.9 U16 C33, C35, R19, R50 U16 is the LP590MFX-3.3 low dropout regulator (LDO) that converts the input voltage from the USB power source to a stable 3.3 V. 6 DRV5055EVM SLYU047A – April 2018 – Revised May 2018 Submit Documentation Feedback Copyright © 2018, Texas Instruments Incorporated Hardware www.ti.com 3.3.10 U17, R28-R34, R40-R42, D13-D16 U17 is the TCA9535 GPIO extender. The MSP430FR4133 and TCA9535 communicate through the I2C protocol, which requires pullup resistors R32 and R33. The TCA9535 is the slave device, whereas the MSP430FR4133 is the master device. U16 communicates the K1 state on pins P00, P01, and P02 to the MSP430FR4133. Pins P03-P07 and P10-P16 are defined as outputs for toggling LEDs D5-D16 according to commands from the MSP430FR4133. Resistors R28-R31 are 10-kΩ resistors meant to limit current through LEDs D13-D16 when a corresponding TCA9535 output pin is toggled low. Resistors R40-R43 are for power saving when any the corresponding TCA9535 output pin is high. By default, TCA9535 GPIOs are all disabled and thus to enable these GPIOs the 10-kΩ, R34, ties pin 1 to 3.3-V VCC. 3.3.11 U19 U19 is the VI-401-DP-RC-S LCD that displays the measurements of a selected device for a given selected measurement format. 3.3.12 M1, C49-C42 M1 is the MSP430FR4133 that samples the analog output from the DRV5055 and converts those outputs into a bit pattern that conveys the correct output measurement on the LCD display. M1 uses capacitors C49-C42 to convert the input voltage to a boosted square wave output signal capable of driving the LCD display. M1 also gathers information from push-button S1, U17, the signal fed through U20, and signals from U5-U12. M1 also commands U17 to turn on the LEDs of interest. 3.3.13 U21 U21 is a switch that serves as a GPIO extender to provide on additional pin with a voltage signal suitable for the LCD.
