17 CIRCUITDESCRIPTION
TheWPME-CDISdigitalisolatorconsistsoftwocapacitiveisolateddigitalchannelsthatmustbepoweredbytwoisolated supply voltages. The device is typically operated using 5V, 3.3V or 2.5V and the primary and secondary sides can be independently powered with any voltage within the operating conditions. The WPME-CDIS integrates the isolation capacitorsinadditiontothemodulatorsanddemodulatorsneededtoconstructthetwoisolatedchannels. Theisolationchannelsarerealizedusingon/offkey(OOK)modulationtotransmithighorlowspeedsignalsthroughsilicon dioxide isolation barriers. The on-chip oscillator is used to modulate the schmitt-triggered input signal. The modulator generatesadifferentialsignalthatistransmittedthroughthecapacitiveisolationlines. Thedemodulatorislocatedonthe output side of the signal channel and used to amplify, filter and reconstruct the input signal with minimum propagation delay and distortion. Finally, the output of the demodulator is given to the output through buffer to improve the driving strength.

20 HANDLINGRECOMMENDATIONS
- The digital isolator is classified as MSL3 (JEDEC Moisture Sensitivity Level 3) and requires special handling due to moisturesensitivity(JEDECJ-STD033D). 2. Thepartsaredeliveredinasealedbag(MoistureBarrierBag=MBB)andshouldbeprocessedwithinoneyear. 3. Whenopeningthemoisturebarrierbag,checktheHumidityIndicatorCard(HIC)forthecolorstatus. Bakepartsprior tosolderingincaseindicatorcolorhaschangedaccordingtothenotesonthecard. 4. Partsmustbeprocessedafter168hour(7days)offloorlife. Oncethistimehasbeenexceeded,bakepartspriorto solderingperJEDECJ-STD033Drecommendation. 5. Maximumnumberofsolderingcyclesistwo. 6.
