DRV821xEVM and DRV8220EVM User's Guide
ABSTRACT
This document is provided with the DRV82xx family customer evaluation modules (EVM) as a supplement to the
DRV8210, DRV8212, and DRV8220 data sheets. This user's guide describes the hardware implementation of
the EVM.
CAUTION
Hot surface . Contact may cause burns. Do not Touch.
DRV8210EVM and DRV8212EVM are rated for power supply voltages between 1.65 VDC and 11
VDC max. The DRV8210 can support peak output currents up to a maximum of 1.6 ADC and the
DRV8212 can support peak output currents up to a maximum of 4 ADC. To maintain component
temperatures below the 130°C rating of the printed circuit board material, TI requires that the
continuous current of both channels be limited to
0.9 A-RMS when operating for extended periods of
time at an ambient temperature of 25°C.
