HALL-ADAPTER-EVM
This user’s guide describes the characteristics, operation, and use of the HALL-ADAPTER-EVM. This
EVM is designed to evaluate the performance of many of the DRV50xx Hall sensors in a variety of
configurations. Throughout this document, the terms evaluation board, evaluation module, and EVM are
synonymous with the HALL-ADAPTER-EVM. This document includes a schematic, reference printedcircuit board (PCB) layouts, and a complete bill of materials.

Overview
Hall effect sensor products from TI, including switches, latches, and linear response products come
primarily in two packages: a 3-pin SOT-23 and a TO-92. To simplify prototyping and experimenting with
these various devices, mounting these devices on a PCB with a bypass capacitor is often necessary.
Sometimes a pull-up resistor is required, as in the case of open drain outputs. This EVM provides 10
breakout (coupon, adapter) boards to facilitate testing, five with an appropriate SOT-23 footprint, and five
with a TO-92 footprint. This EVM also comes with a magnet for quick experimenting and gross functional
testing, as well as a PCB ruler to approximate activation distances. Table 1 lists a summary of compatible
Hall effect sensors.

Hardware
The HALL-ADAPTER-EVM 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 HALL-ADAPTER-EVM consists of one PCB with an option to break apart
eight individual PCBs.
2.1
Features
The layout of the HALL-ADAPTER-EVM printed-circuit board (PCB) is designed to provide the following
features:
• Evaluation of most of the Hall sensor products from TI
• Ease of access to device pins with 100-mil-spaced test points
• Ruler for measuring activation distance and responsiveness to magnetic fields
• Ten breakout boards allow for multiple sensor evaluation (up to five SOT-23 and five TO-92 packaged
sensors)
3
Quick Start Setup and Use
The following steps list the instructions to set up and use the HALL-ADAPTER-EVM:
Step 1. Before separating the coupon boards from the main PCB, consider that soldering parts to the
boards may be easier before snapping them apart. Follow safe soldering practices and
observe ESD precautions when handling devices.
Step 2. Solder the appropriate sample devices to the PCBs, and solder an appropriate bypass
capacitor for the device as well.
Step 3. Determine if the device requires a pull-up resistor, and solder an appropriate resistor, if
needed.
Step 4. If cleaning the board is required at this time, follow appropriate and safe PCB cleaning
procedures.
Step 5. Use mini-grabbers or other clip-leads to attach a power supply, ground, and some kind of
voltage meter to the three test points. Another option is to solder prototyping headers (such
as SAMTEC TS-132-G-AA, included) to the test points and plug the board into a protoboard
with 100-mil-spaced holes.
Step 6. After appropriately connected and powered, move and rotate the magnet near the device.
Observe the change in output voltage as the magnet position changes proximity and
orientation.

Circuitry
This section summarizes the HALL-ADAPTER-EVM components. For the following components, x = 0, 1,
2, 3, or 4, corresponding to the appropriate breakout board.
4.1
C1x1 and C2x1
These are pads provided to mount an 0603-size supply bypass capacitor.
4.2
R1x1 and R2x1
These are pads provided to mount an 0603-size pull-up resistor.
4.3
U1x1 and U2x1
U1x1 is the location in a TO-92 package where the Hall sensor device must be soldered. U2x1 is the
location in a SOT-23 package where the Hall sensor device must be soldered. Five TO-92 breakout
boards and five SOT-23 breakout boards are supplied with the HALL-ADAPTER-EVM. These boards
enable users to test the devices, and determine the gain settings that are best suited for a given
application.
