IRLML5203 Cov lus nug nquag nug

Kev txhaum hauv qhov transistor no: MOS transistors muaj cov haujlwm sib txawv hauv cov khoom sib txawv thiab cov circuits. Piv txwv li, hauv LLC, qhov ceev ntawm cov diode loj kuj yog qhov tseem ceeb cuam tshuam rau kev ntseeg siab ntawm MOS transistors. Vim lub fact tias diodes lawv tus kheej yog parasitic tsis, nws yog ib qhov nyuaj rau paub qhov txawv ntawm qhov to diode faults thiab leakage qhov chaw voltage faults. Cov kev daws teeb meem rau diode faults yog tsom xam los ntawm kev sib txuas nrog nws tus kheej circuit.

Piv txwv li: Siv lub lithium roj teeb tiv thaiv lub rooj tsavxwm ua lub chaw them nyiaj thiab tso tawm

Feem ntau, MOS yog nyob rau hauv lub xeev nyob rau hauv lossis tawm, yam tsis xav txog qhov kev hloov ceev ntawm MOS, lub kaw lus ceev yog tsim los ntawm tag nrho cov Circuit Court.

Ua tib zoo mloog cov ntsiab lus hauv qab no:

1. Ua tib zoo mloog rau DS voltage thiab tawm ntawm cov npoo txaus rau kev tsim thiab xaiv. Raws li BVDDS ntawm 1.5 npaug ntawm MOS transistor

2. Ua tib zoo saib xyuas qhov ua haujlwm tam sim no thiab tiv thaiv tam sim no. Tus nqi ntawm kev paub yog 3-4 zaug lossis ntau dua, uas yog ID (DC) ntawm MOS.

3. Ntau MOSs txuas nrog rau qhov sib npaug, thiab cov npoo tam sim no yuav tsum loj npaum li qhov ua tau.

4. Lub hom phiaj ntawm kev siv cov tam sim no siab yuav tsum ua tib zoo xav txog kev ntim cov cua kub dissipation thiab sab hauv tsis kam.

5. Nws yog ib qho tseem ceeb kom nkag siab txog qhov tsav tsheb voltage thiab sim ua kom MOS ua haujlwm hauv lub xeev qhib tag nrho. Rau microcontroller tsav kev daws teeb meem, nws raug nquahu kom siv MOS nrog lub xeev qis qhib kom ntau li ntau tau.

Tsis tas li ntawd, thaum xaiv MOS transistors, yuav tsum tau them nyiaj mloog mus rau hom channel, BVDDS, ID conduction tam sim no, VGS (th), RDSON thiab lwm yam tsis.
