NST118 Datasheet | NOVOSENSE

Overview Applications The NST118 is a low-power, high accuracy digital temperature sensor patible with SMBus and I2C interfaces, and supports 4 device addresses, and provides SMBus reset and alert functions. The device operates in the power supply voltage range of 1.71V to 3.6V, and offers typical accuracy of 0.1°C from 25°C to 45°C and maximum accuracy of 1°C in the full temperature range -40°C to 125°C. The NST118 on-chip 12-bit analog-to-digital converter (ADC) provides resolution down to 0.0625°C. It is highly linear and does not require plex calculations or lookup tables to derive temperature. NST118 has an operating temperature range of -40°C to 125°C and is available in DFN(6) package, making it suitable for on-board and off-line applications in the automotive, industrial, and consumer markets. Because of low power consumption, it can also be applied to Io T. In addition, it is a good substitute for negative temperature coefficient (NTC) and positive temperature coefficient (PTC) thermistors. - General System Thermal Management - puter Peripheral Thermal Protection - Notebook puters - Industrial Internet of Things (Io T) - munications Infrastructure - Power-system Monitors - Thermal Protection - Environmental Monitoring and HVAC Device Information Part Number NST118-CDNR Package DFN(6) Body Size 2mm×2mm Typical Application Key Features Supply Voltage 1.71V to 3.6V - High Accuracy over - 40°C to 125°C Wide Temperature Range 25 °C ~ 45 °C:  0.1°C (Typical) -20 °C ~ 60°C:  0.5°C (Maximum) -40 °C ~125°C:  1°C (Maximum) - Proportional to Temperature with 0.0625°C Resolution - Power up Defaults Permit Stand-Alone Operation as Thermostat - Supports up to 4 Device Addresses - Supply Operation range from 1.71V to 3.6V - Operating Current: 6.5μA (Typical, 4Hz conversion cycle) 2.9μA (Typical, 1Hz conversion cycle) Pullup Resistor 5.1KΩ Two Wire Host Controller SCL 1 6 SDA GND 2 NST118 5 ALERT 3 ADD0 4 Supply Bypass Capactior 0.01u F Figure 1...
