Overview

The EMC1815T-AE/9R is a high-accuracy, multi-channel digital temperature sensor featuring one internal and four external remote temperature monitors. Operating over a 1.62V to 3.6V supply range, it includes advanced thermal management features like resistance error correction, beta compensation, and a unique rate of change calculation with preemptive alerts.

Why Choose This Part

This sensor reduces firmware overhead by performing rate of change calculations and 'hottest diode' comparisons in hardware. It ensures high precision across various transistor types via automatic beta compensation and configurable ideality factors, while resistance error correction eliminates offsets from long PCB traces.

Applications

Multi-Zone Thermal Monitoring
Utilizing up to four external diodes to monitor hotspots across a PCB or within an enclosure from a single I2C/SMBus address.
Low-Power IoT Sensing
Ideal for battery-operated devices due to its 1.62V minimum supply voltage and low 15uA standby current.
Predictive Maintenance
Leverages the hardware-based temperature rate of change calculation to trigger alerts before critical thermal limits are reached.
Industrial System Protection
Reliable monitoring in environments from -40C to +125C with programmable limits and configurable alert pins.

Getting Started

Interface the device via the I2C or SMBus pins to a microcontroller and configure the conversion rate and alert limits in the internal registers. Designers should place a 0.1uF bypass capacitor close to the VDD pin and follow layout guidelines for remote diode traces to minimize noise coupling.
