Advantages Different accuracy classes with 100% upward compatibility No calibration by customer necessary any more, absolute calibration specified Simple to integrate, reducing cost and time for application-development Robust and elementary signal transmission requires only one singal line Optimum solution for temperature control, thanks to fast data measurement Packages for standard SMD, THT or application specific assembly Miniaturised solutions with Bare-chip (COB, COF, CSP) or e-line package Very fast response time with Bare-chip (COF – Chip on Flex) Very small power consumption – ideal for mobile and standard applications Field (re-)configuration or (re-)calibration available (option for high volume customers only) Outstanding long term stability Packages SOP8 Package (150mil, Standard SMT Technology, SOIC-8) based on IEC 191-2Q: Type 076E35 B C Pin 1 = V+ Pin 2 = Signal Pin 4 = Ground 1 B 2 3 8 7 6 5 Dimensions (max) B = 4.98 mm C = 6.20 mm T T = 1.73 mm 4 e-line (small THT package, TO-92 like) e-line e-line Package (similar to TO92) Dimensions (max.): A = 2.8 mm D = 4.4 mm E = 4.4 mm L = 13.0 mm A L D 321 V+ Ground Signal E Specification See next pages “TSic101 Temperature Sensor Device, Specification” TSic™-101 Temperature Sensor IC Specification Features • • • • • • • • • • Analog 0-1 Volt signal output o Accuracy: ±0.5 C at room temperature o ±1.0 C over span of 40° C o Resolution: 0.1 C Wide range measurement: o o –50 to +150 C Signal update every 0.1 second (other update frequencies on request) Supply Voltage V+ = 3.0V to 5.5V, high accuracy operation in range V+ = 4.5V to 5.5V Precision temperature sensor at low cost Package: 8-pin SOIC or 3-pin e-line Low quiescent current of less than 80µA at 25° and 3.3V to minimize self-heating and C power consumption System-on-a-chip based on advanced mixed signal technology incorporating: precision temperature sensing bandgap reference with PTAT output digital signal processor (DSP) core electrically erasable (EE) memory digital serial interface using single wire for signal output TM Description TSicTM Series The TSic series of temperature sensor ICs were specifically designed as a high-performance, cost-effective solution for temperature sensing in building automation, automotive, industrial, office automation, white goods and low power / mobile applications. TM The TSic employs high precision bandgap reference with proportional-to-absolute-temperature (PTAT) output; low-power precision ADC; and on-chip DSP core with electrically erasable (EE) memory to precisely calibrate the output temperature signal. TM TSic series of temperature sensor ICs offers devices with two linear analog signal output options such as standard 0~1Vout signal (V+ = 3.0V to 5.5V) or ratiometric (10~90% V+ i.e. 0.5~4.5Vout @ V+=5V) or the digital serial output signal to interface with µP controllers.
