Selelekela
Ha e sebelisoa ka mokhoa o tsoelang pele, mojule oa VL53L8CX hangata o sebelisa 215 mW ea matla. Ka lebaka leo, ho hloka taolo e hlokolosi ea mocheso ho netefatsa hore sesebelisoa se sebetsa hantle le ho qoba mocheso o feteletseng.
Letlapa la 1. Mekhahlelo e ka sehloohong ea mocheso
| Paramethara | Letšoao | Min. | Tlanya. | Max. | Yuniti |
| Tšebeliso ea matla | P | — | 215 (1) | 320 | mW |
| Mocheso oa mateano (2) | TJ | — | — | 110 | °C |
| E-shoa ho hanyetsa mocheso | Oa shoa | — | — | 43 | °C/W |
| Boemo ba mocheso o sebetsang | T | -30 | 25 | 85 | °C |
- AVDD = 2.8 V le IOVDD = 1.8 V ea tšebeliso e tloaelehileng ea hona joale.
- Ho thibela ho tima mocheso, mocheso oa mateano o tlameha ho bolokoa ka tlase ho 110 °C.
Lintho tsa motheo tsa moralo oa mocheso
Letšoao θ ka kakaretso le sebelisoa ho supa khanyetso ea mocheso e leng tekanyo ea phapang ea mocheso eo ntho kapa thepa e hananang le phallo ea mocheso. Bakeng sa mohlalaample, ha o tloha nthong e chesang (joaloka silicon junction) ho ea ho e phodileng (joalo ka mocheso o ka morao oa module kapa moea o teng).
Mokhoa oa ho hanyetsa mocheso o bontšitsoe ka tlase mme o lekanngoa ka °C/W:
θ = ΔT/P
Moo ΔT e leng ho phahama ha mocheso oa matekoane 'me P ke ho felloa ke matla. Kahoo, bakeng sa mohlalaample, sesebelisoa se nang le ho hanyetsa mocheso oa 100 ° C / W se bontša phapang ea mocheso oa 100 ° C bakeng sa ho senya matla a 1 W ha ho lekanngoa pakeng tsa lintlha tse peli tsa boitsebiso. Foromo e tjena:
- θpcb = TJ − TA ÷ P − θ shoa
- θpcb = 110 − TA ÷ P − 43
Moo:
- TJ ke mocheso oa mateano
- TA ke mocheso oa tikoloho
- θdie ke "die thermal resistance".
- θpcb ke ho hanyetsa mocheso oa PCB kapa flex
Ho hanyetsa mocheso oa PCB kapa flex
Mocheso o phahameng o lumelletsoeng oa mateano oa VL53L8CX ke 110°C. Boholo bo lumelletsoeng PCB kapa flex flex thermal resistance bo baloa joalo ka ha ho bonts'itsoe ka tlase. Palo ena ke ea ho felloa ke matla a 0.320 W, le ts'ebetso ea sesebelisoa ho 85 ° C (boemo bo bobe ka ho fetisisa ba mocheso o phahameng o boletsoeng oa tikoloho).
- θpcb = TJ − TA ÷ P − θ shoa
- θpcb = 110 − 85 ÷ 0.320 − 43
- θpcb = 35°C/W
Hlokomela: Ho etsa bonnete ba hore mocheso o phahameng oa mateano ha o fetisetsoe, le ho etsa bonnete ba hore o sebetsa hantle ka ho fetisisa, u se ke ua feta sepheo se ka holimo sa ho hanyetsa mocheso. Bakeng sa sistimi e tloaelehileng e lahlang 320 mW, ho phahama ho hoholo ha mocheso ke <11°C. Sena se khothaletsoa bakeng sa ts'ebetso e nepahetseng ea VL53L8CX
Litaelo tsa sebopeho le mocheso
Sebelisa litataiso tse latelang ha u rala module PCB kapa flex:
- Eketsa sekoaelo sa koporo ho PCB ho eketsa conductivity ea mocheso oa boto.
- Sebelisa module, thermal pad B4 e bontšitsoeng ho Setšoantšo sa 2. VL53L8CX pinout le thermal pad. Kenya khutlonnetsepa e le 'ngoe e kholo ea pente ea solder. E lokela ho ba boholo bo lekanang le mocheso oa mocheso (li-rectangles tse robeli) ho ea ka Setšoantšo sa 3. Keletso ea mocheso oa mocheso le ka PCB. STMicroelectronics e khothaletsa ho roka li-vias tse robeli ho tloha holimo ho ea tlase, kahoo maske a ka tlase a bulehile 'me pad e pepesitsoe.
- Sebelisa ho latedisa ka bophara bakeng sa matshwao ohle haholoholo matla le matshwao a fatshe. Latela 'me u li hokele ho lifofane tsa motlakase tse haufi moo ho khonahalang.
- Kenya mocheso ho chassis kapa liforeimi ho tsamaisa mocheso hole le sesebelisoa.
- U se ke ua beha haufi le likarolo tse ling tse chesang.
- Beha sesebelisoa sebakeng sa matla a tlase ha se sa sebelisoe.
