THERMO 5 Click measures temperature in default range of 0°C to 127°C and extended range of -64°C to 191°C with ±1°C accuracy. It carries the EMC1414 temperature sensor. The Click is designed to run on a 3.3V power supply. THERMO 5 Click communicates with the target microcontroller over I2C interface, with additional functionality provided by the INT pin on the mikroBUS™ line.
The Click can monitor four temperature channels - three external and one internal.
THERMO 5 Click can be used to measure temperatures with up to two/three externally connected diodes.
Each external diode channel is configured with Resistance Error Correction and Beta Compensation based on user settings and system requirements.
The device contains programmable High, Low, and Thermo limits for all measured temperature channels.
If the measured temperature goes below the Low limit or above the High limit, the ALERT pin can be asserted (based on user settings).
If the measured temperature meets or exceeds the Thermo Limit, the THERM pin is asserted unconditionally, providing two tiers of temperature detection.
The EMC1414 monitors four temperature channels. It provides ±1°C accuracy for both external and internal diode temperatures.
Resistance Error Correction feature automatically eliminates the temperature error caused by series resistance allowing greater flexibility in routing thermal diodes.
Beta Compensation feature eliminates temperature errors caused by low, variable beta transistors common in today’s fine geometry processors.
