Low power consumption 1.8V temperature sensor, have you heard of it?

What is a low-power 1.8V temperature sensor? What does it do? Temperature measurement is extremely important to ensure the functionality of Internet of Things (IoT) and personal computing devices. Developers must integrate temperature sensors in devices to reduce energy consumption and reduce application costs. system voltage in . To meet these needs, Microchip Technology Inc. has launched five new 1.8V temperature sensors, including the industry's smallest five-channel, standard lead spacing temperature sensor. The EMC181x temperature sensor series also introduces a system temperature change rate reporting function, which can provide early warning of system temperature fluctuations.

Monitoring temperature at multiple locations with a single integrated temperature sensor reduces board complexity and simplifies design. The EMC181x temperature sensor series operates at 1.8V and provides multiple remote detection channels to accommodate different design needs from 2 to 5 channels. This family of products is ideal for applications migrating from 3.3V systems to lower voltage rails, such as battery-powered IoT applications, personal computing devices, field programmable gate arrays (FPGAs) and graphics processing units (GPUs). Additionally, the EMC181x family is register- and voltage-compatible with Microchip's popular 3.3V EMC14xx temperature sensors, making migration to 1.8V applications testable and feasible. The sensor is available as a three-channel sensor in an 8-pin 2 x 2mm package and as a five-channel sensor in a 10-pin 2 x 2.5mm package, thereby also reducing the number of devices required for remote temperature monitoring.

By measuring the rate of change of system temperature, the EMC181x device enables two-dimensional temperature sensing for the first time in the industry. In addition to reporting regular temperatures, this feature notifies customers of the rate of temperature change in their systems and helps customers better tune their applications by sharing the data. The system is ideal for closed-loop control systems and other applications that prioritize low-voltage rails, providing advance notification of increases or decreases in temperature, preventing potential system failures.

"As customers migrate to lower voltage rails, demand for multi-channel, low voltage temperature sensors continues to grow," said Bryan Liddiard, vice president of Microchip's Mixed Signal and Linear Products Group. "The EMC181x series demonstrates Microchip's leadership in temperature management. This provides customers with flexible design options, as well as new rate-of-change reporting capabilities."

Operating at only 1.8V, the EMC181x multi-channel sensor family is compatible with Microchip's extensive portfolio of low-voltage and low-power microcontrollers.

The ADM00773 evaluation board provides everything needed to demonstrate the 1.8V three-channel, two-wire EMC1833 temperature sensor and can also be used to functionally evaluate other EMC181x family products. It helps evaluate programmable features such as rate of change, temperature alarm limits and impedance error correction (REC). It also provides remote temperature measurement and data logging capabilities. The evaluation panel connects to a PC via a USB interface board and uses its own Microchip temperature management software graphical user interface (GUI) on the PC. The above is the analysis of low-power 1.8V temperature sensor, I hope it can help you.
