Product details

Five-channel remote sensing with ±1.5°C accuracy

This is a five-channel digital remote temperature sensor from Microchip. It measures its own die temperature plus up to four external diode-connected transistors, reporting results over an I²C/SMBus interface.

1.62V to 3.6V supply — fits common logic rails

The supply voltage range from 1.62V to 3.6V means this sensor can run directly off a 1.8V or 3.3V rail without an extra regulator. That simplifies the power tree in space-constrained designs like server DIMM thermal monitoring or portable equipment. The 10-VFDFN package (2.5x2 mm body) is a surface-mount DFN with an exposed pad for heat sinking.

One-Shot, programmable limit, standby mode

Built-in features include a one-shot conversion mode for single-read operations without continuous bus traffic, a programmable temperature limit with alert output, and a standby mode that drops quiescent current between measurements. These are useful in battery-powered or intermittently-sampled systems where power budget matters.

Frequently asked questions

Is EMC1815T-1E/9R compatible with 3.3V systems?

Yes. The supply range is 1.62V to 3.6V, so the sensor runs directly on a 3.3V rail without a separate LDO.
