DRV5032-SOLAR-EVM
2.1
Features
The layout of the DRV5032-SOLAR-EVM printed-circuit board (PCB) is designed to provide the following
features:
•
Ultra-low power
•
Onboard solar panel
•
LED indicator to conveniently show when device output has been triggered
See the DRV5032 data sheet (
SLVSDC7
) for comprehensive information about the DRV5032FB device.

Quick Start Setup and Use
The following are instructions to set up and use the DRV5032 on the DRV5032-SOLAR-EVM:
Setup using the onboard test hardware:
Step 1.
Power supply (solar panel): Connect jumpers across the pins for J1 and J3. Ensure that the
solar panel is in a well lighted area.
Step 2.
Device output (LED indicator): Connect a jumper across the pins for J2.
Step 3.
Test the DRV5032 Hall-effect sensor as described in
Section 3.1
.
Setup using external test hardware:
Step 1.
Power supply: Remove the jumpers across the pins for J1 and J3. Connect an external DC
supply voltage between 1.65-V and 5.5-V to the VCC pin side of J1,and connect ground
reference of that supply to the GND pin side of J3.
Step 2.
Device output: Remove the jumper across the pins for J2. Connect desired measurement tool
to the OUT pin side of J2.
Step 3.
Test the DRV5032 Hall-effect sensor as described in
Section 3.1
.
NOTE:
When using an external voltage source, you must also use an external voltage measurement
tool to view the device output, however, you may still view the device output with an external
voltage measurement tool while using the onboard solar panel.

Measurements
The DRV5032-SOLAR-EVM enables the user to test the functionality of the DRV5032 Hall-effect sensor
using either the onboard hardware or external hardware, which must first be setup as described in
Section 3
.
The following test procedures are to be used for both onboard and external hardware.
Step 1.
Trigger the DRV5032 device output: Lower either the north or south pole of a magnet directly
over the DRV5032FB Hall-effect sensor.
Step 2.
Observe the output: If using the onboard hardware, observe the indicator light D1 blink when
the magnet gets close to the Hall-effect sensor. Alternatively, observe the voltage drop on an
external voltage measuring device.
