♠ TPS7B82-Q1 Izimoto 300-mA, High-Voltge, Ultra-Low-IQ Low-Dropout Regulator
Kuzinhlelo zokusebenza ezixhumeke kwibhethri yezimoto, i-low quiescent current (IQ) ibalulekile ukuze wonge amandla futhi andise impilo yebhethri. I-IQ ephansi kakhulu kufanele ifakwe kumasistimu ahlala evuliwe.
I-TPS7B82-Q1 iyisilawuli somugqa esiphuma kancane esiklanyelwe ukusebenza ngebanga elibanzi lokufakwayo-voltage ukusuka ku-3 V ukuya ku-40 V (ukuvikelwa kokulahla umthwalo ongu-45-V). Ukusebenza kwehle kuze kufike ku-3 V kuvumela i-TPS7B82-Q1 ukuthi iqhubeke nokusebenza ngesikhathi se-cold-crank kanye nezimo zokuqala nokumisa. Ngamanje okuthule okungu-2.7-µA okujwayelekile okuthule lapho kulayishwa khona ukukhanya, le divayisi iyisixazululo esilungile sokunika amandla ama-microcontrollers (ama-MCU) nama-CAN/LIN ama-transceiver kumasistimu alindile. Idivayisi ihlanganisa ukuvikela okuhlanganisiwe kwe-short-circuit kanye ne-overcurrent.
Le divayisi isebenza emazingeni okushisa avela ku--40°C kuya ku-+125°C futhi namazinga okushisa okuhlangana asuka ku- -40°C kuya ku-+150°C. Ukwengeza, le divayisi isebenzisa iphakheji ye-thermal conductive ukunika amandla ukusebenza okuqhubekayo naphezu kokuhlakazeka okukhulu kulo lonke idivayisi. Ngenxa yalezi zici, idivayisi yakhelwe njengomthombo wamandla wezinhlelo zokusebenza zezimoto ezahlukahlukene.
