Especificações Técnicas

OUTROS PART NUMBERS PARA ESTE COMPONENTE: NCP45491XMNTWG, NCP45491 THE NCP45491 IS A HIGH-PERFORMANCE MONOLITHIC IC WHICH CAN BE USED TO MONITOR BUS VOLTAGE AND CURRENT ON FOUR HIGH-VOLTAGE POWER SUPPLIES SIMULTANEOUSLY. THE HV BUS VOLTAGES AND CURRENTS ARE TRANSLATED TO A LOW-VOLTAGE POWER DOMAIN AND MULTIPLEXED ONTO A SINGLE DIFFERENTIAL OUTPUT FOR MEASUREMENT EXTERNALLY BY COMMON ADCS. THE DEVICE IS CONFIGURABLE TO OPERATE EITHER STANDALONE OR AS A PAIR, PERMITTING UP TO EIGHT SEPARATE HV POWER SUPPLIES TO BE MONITORED AND MEASURED.   FEATURES - TRANSLATES AND SCALES SHUNT AND BUS VOLTAGES UP TO 26 V - SINGLE DEVICE MONITORS FOUR SUPPLIES - MAY BE PAIRED FOR MONITORING UP TO EIGHT SUPPLIES - VERY LOW POWERDOWN CURRENT - ALL CHANNELS INDIVIDUALLY GAIN PROGRAMMABLE BY EXTERNAL RESISTOR SELECTION - FAST SETTLING TIME - REAL-TIME INDICATION OF ALL BUS VOLTAGES VALID - ADJUSTABLE OUTPUT COMMON-MODE VOLTAGE ADAPTS TO MOST EXTERNAL ADCS - LEAD-FREE DEVICE   APPLICATIONS - COMPUTERS/NOTEBOOKS - GRAPHICAL CARDS - POWER MANAGEMENT/POWER CONTROL LOOPS - BATTERY CHARGERS     PRODUCT: CURRENT MONITORS SENSING METHOD: HIGH SIDE SUPPLY VOLTAGE - MAX: 3.8 V SUPPLY VOLTAGE - MIN: 2.8 V OPERATING SUPPLY CURRENT: 180 UA MINIMUM OPERATING TEMPERATURE: - 40 C MAXIMUM OPERATING TEMPERATURE: 85 C MOUNTING STYLE: SMD/SMT PACKAGE / CASE: QFN-32 PACKAGING: REEL PACKAGING: CUT TAPE PACKAGING: MOUSEREEL BRAND: ONSEMI INPUT VOLTAGE RANGE: 2.8 V TO 3.8 V 45491 CI PMIC POWER SUPPLY CONTROLLER QFN-32 MAIORES DETALHES DE 45491 NO SITE DO FABRICANTE: HTTPS://WWW.ONSEMI.COM/PDF/DATASHEET/NCP45491-D.PDF TAGS DE 45491: NCP45491XMNTWG, NCP45491, 45491, NNCP45491, 26V 4CH VOLTAGE BUS AND 4CH HIGH SIDE CURRENT SHUNT MONITOR, REGULADOR DE POTÊNCIA NVIDIA, CI CONTROLADOR DE FAN RTX3080, CI CONTROLADOR DO FAN RTX3090, TRANSISTOR RTX3080, TRANSISTOR RTX3090, DRIVER FAN RTX3080, DRIVER FAN RTX3090, CI FAN RTX3080, CI FAN RTX3090, NAND AHCT, RTX NÃO LIGA FAN, RTX3090 NÃO LIGA FAN, FALHA DE FALHA FAN RTX3080, FALHA DE FAN RTX3090, CI PLACA DE VIDEO RTX3080, CI PLACA DE VIDEO RTX3090, PMIC - POWER MANAGEMENT ICS, PMIC POWER MANAGEMENT ICS, MONITOR DE CORRENTE, MONITOR DE VOLTAGEM, CI MONITOR DE CORRENTE NVIDIA, CI PLACA DE VIDEO RTX
