♠ I-LP8866S-Q1 I-Automotive Display LED-backlight Driver eneziteshi eziyisithupha eziyi-150-mA
I-LP8866S-Q1 ingumshayeli we-LED osebenza kahle kakhulu ezimotweni onesilawuli se-boost.Amasinki ayisithupha e-highprecision current asekela ukushintshwa kwesigaba okulungiswa ngokuzenzakalela ngokusekelwe enanini lamashaneli asetshenziswayo.Ukukhanya kwe-LED kungalawulwa emhlabeni wonke ngesixhumi esibonakalayo se-I²C noma okokufaka kwe-PWM.
Isilawuli se-boost sinokulawula okuphumayo okuguquguqukayo okususelwe kuma-voltage e-headroom yamasinki amanje we-LED.Lesi sici sinciphisa ukusetshenziswa kwamandla ngokulungisa i-boost voltage ibe ileveli eyanele ephansi kuzo zonke izimo.Ifrikhwensi yebanga elibanzi elungisekayo ivumela i-LP8866S-Q1 ukuthi igweme ukuphazamiseka kwebhendi yerediyo ye-AM.
I-LP8866S-Q1 isekela ukufiphala kwe-PWM ehlanganisiwe eyakhelwe ngaphakathi kanye nokufiphala kwamanje kwe-analog, okunciphisa i-EMI, kunwebe ukuphila kwe-LED, futhi kukhuphule ukusebenza kahle okuphelele kokubona.
• I-AEC-Q100 ifanelekele izicelo zezimoto:
- Izinga lokushisa ledivayisi grade 1:
-40°C kuya +125°C, TA
- Isigaba 2 sedivayisi ye-HBM ESD
- Idivayisi ye-CDM ESD yezinga lesigaba C4B
• Ibanga lokusebenzisa amandla kagesi 3 V kuya ku-48 V
• Osinki bamanje abanembile abayisithupha
- Kufika ku-150-mA DC yamanje kusinki ngamunye wamanje
- Ukuqhathanisa kwamanje 1% (okujwayelekile)
- Isilinganiso sokufiphala 32 000:1 kusetshenziswa imvamisa ye-PWM ye-LED engu-152-Hz
- Kuze kufike ku-16-bit LED ukufiphala kwesinqumo nge-I2C, noma okokufaka kwe-PWM
- 8 Ukucushwa kwezintambo ze-LED ezilungisekayo
• Ukufiphala kwe-PWM yesigaba esizenzakalelayo
• 12-bit analog dimming
• Kufikela ku-48-V VOUT boost noma isilawuli se-SEPIC DC/DC
- Ukushintsha imvamisa ku-100 kHz kuye ku-2.2 MHz
- Khulisa i-spectrum yokusabalala kwe-EMI encishisiwe
- Thuthukisa okokufaka kokuvumelanisa ukuze usethe i-boost switching frequency kusuka ewashini langaphandle
- I-voltage yokuphuma ikhishwa ngokuzenzakalelayo lapho i-boost ikhutshaziwe
• Ukuhlola amaphutha okubanzi
• Ukukhanya kwangemuva kwe:
- I-infotainment yezimoto
- Iqoqo lezinsimbi zezimoto
– Izibuko ezihlakaniphile
- Izibonisi ze-Head-up (HUD)
