4.1 Output Measurements

The DRV2603 uses PWM modulationtocreatetheoutputsignalforbothERM and LRA actuators.To measure and observetheDRV2603 outputwaveform,connectan oscilloscopeorothermeasurement equipmenttothefilteredoutputtestpoints,“OUT+ ”and “OUT- “. Figure12.TerminalBlock and TestPoints The DRV2603 drivesLRA and ERM actuatorsusinga 20kHz PWM modulatedwaveform,butonlythe frequenciesaroundtheLRA resonantfrequencyortheERM DC drivevoltagearerelevanttothehaptic actuatorvibration.The higherfrequencyswitchingcontentdoes notcontributetothevibrationstrengthof theactuatorand can make itdifficulttointerpretthemodulatedoutputwaveform on an oscilloscope.The oscilloscopeimage on theleftshows theDRV2603 unfilteredwaveform and theimage on therightshows a filteredversionused forobservationand measurement. Figure13.DRV2603 UnfilteredWaveform Figure14.DRV2603 FilteredWaveform To observethemodulatedoutputwaveform and ensurethatthe20kHz switchingwaveform and associatedharmonicsarenotcaptured,use eithera digitaloranalog,lowpass filterwhen viewingthe outputwaveform.TIrecommends usinga 1st-order,low-passfilterwitha cutoffbetween 1kHz and 3.5kHz. Below arerecommended outputfiltersforuse whilemeasuringand characterizingtheDRV2603. Certain oscilloscopeshave a built-indigital,low-passfilter,so no externalcomponents arerequired.
