Microchip Technology announces EMC181x temperature sensor

October 16, 2018 — Microchip Technology announced five 1.8V temperature sensors, including the five-channel temperature sensor with standard lead spacing. The EMC181x temperature sensor family also introduces system temperature rate-of-change reporting, a feature that provides advanced warning on how the temperature of a system is fluctuating.

Monitoring temperature at multiple locations with a single, integrated temperature sensor is intended to reduce board complexity and simplify design. The EMC181x temperature sensor family offers a variety of remote channels at 1.8V operation to fit different design needs, ranging from two to five channels. The family is suitable for applications migrating from 3.3V systems to lower voltage rails, such as battery operated 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 3.3V EMC14xx temperature sensors, making migration to 1.8V testable and achievable. With the three-channel sensor available in an 8-pin 2 x 2 mm footprint and the five-channel in a 10-pin 2 x 2.5 mm footprint, the sensors can also reduce the number of devices needed for remote temperature monitoring.

With the ability to measure the system temperature rate of change, the EMC181x devices offer two-dimensional temperature sensing. In addition to reporting on the regular temperature, the feature notifies customers of the rate of temperature change in a system and shares data that can help regulate applications. Intended for closed control loop systems and other applications that prioritize lower voltage rails, the system provides an early notification of rising or falling temperatures, protecting against potential system failure.

The ADM00773 evaluation board provides everything needed to demonstrate the 1.8V three-channel two-wire EMC1833 temperature sensor and gives functional insight into the other EMC181x family members. It facilitates evaluation of programmable features such as rate of change, temperature alert limits and Resistance Error Correction (REC), in addition to providing off-board temperature measurements and data logging. The evaluation board connects to a PC through a USB interface board and comes with the Microchip Thermal Management Software Graphical User Interface (GUI).
