PMIC - Thermal Management is an important field of study to understand the thermal related power management and control of electronic devices. It encompasses the integrated circuit, electronic components and systems used to provide power conversion and thermal control to systems. The main areas of research involve the understanding of the principles and application of thermal management systems including: heat transfer, thermal design and materials science. This article will discuss SE97TP,147 application field and working principle.

SE97TP,147 Application Field and Working Principle

SE97TP,147 is a low-power temperature sensor IC, designed to provide accurate temperature readings, specifically for automotive and industrial applications. The chip is comprised of a Temperature Sensor Die and two-bit shift register for serial digital output. This shift register is connected to Read and Chip Select pins, as well as power and ground. The Read pin is also connected to an external clock and valid data is available after two high-frequency clock cycles. The Chip Select pin is used to enable and disable the sensor, thus providing the user with power management capabilities. The internal die temperature is sampled and converted to a digital two-bit output via the two internal analog-to-digital converters.

SE97TP,147 has an operating range of -40° C to +125° C, which is suitable for many automotive and industrial applications. The chip is also designed to be cost-effective and consume minimal power, as it only requires a single 1.5V supply voltage to operate. The main advantage of this chip is its low power, as it consumes only 350nA of current at room temperature. Another key feature of SE97TP,147 is its \'fail-safe\' feature. This feature allows the chip to automatically shut off the power to the temperature sensor in the event of an over-temperature situation.

SE97TP,147 provides digital temperature readings, in two’s complement format in 8-bit, 10-bit and 12-bit resolution. The lower resolutions (8-bit and 10-bit) are suitable for applications that require more accurate temperature readings, while the higher resolution (12-bit) is suitable for the most demanding temperature measurement applications. The chip includes an internal temperature sensor that is used to convert the temperature readings from analog to digital form. Additionally, the chip provides an analog voltage output of +2.5V, which is then connected to the ADC pins on the main application CPU/microcontroller/DSP.

In terms of its features and capabilities, SE97TP,147 provides a versatile and low-power temperature sensing solution that has numerous applications in the automotive and industrial market. It can be used to measure the temperature of both ambient air and the internal temperature of ICs, as well as to help improve the accuracy of temperature readings to control the power consumption of electronic devices. This IC is also well suited for use in sensor networks, particularly in applications where multiple temperature sensors are deployed in a distributed manner.

Conclusion

SE97TP,147 is an advanced low-power temperature sensor IC that is perfect for automotive and industrial applications. It provides accurate temperature readings, offers power savings and provides a convenient two-bit shift register for serial digital output. The chip includes an internal temperature sensor and offers 8-bit, 10-bit and 12-bit resolution. The \'fail-safe\' feature enables the chip to automatically shut off the power to the temperature sensor in the event of an over-temperature situation. It is a cost-effective and highly reliable solution for temperature sensing applications.
