TCN75-3.3MOA

The TCN75-3.3MOA from Microchip Technology is a serially programmable digital temperature sensor designed for ambient temperature monitoring. It features a standard 2-wire serial interface, compatible with I2C and SMBus protocols, allowing for easy communication with host controllers.

This sensor offers a wide operating temperature range of -55°C to +125°C and operates from a supply voltage of 2.7V to 5.5V. It provides a resolution of 8 bits and an accuracy of ±3°C. The device includes programmable trip points and hysteresis, with power-up defaults allowing for stand-alone thermostat operation.

Key features include a thermal event alarm output that can function as an interrupt or comparator, and a shutdown mode for low standby power consumption. Up to eight TCN75 devices can share the same bus for multizone monitoring. The TCN75-3.3MOA is housed in an 8-pin SOIC package suitable for surface mounting.

Applications for this temperature sensor include thermal protection for CPUs, solid-state thermometers, fire/heat alarms, and general thermal management in electronic systems such as computers, telecom racks, power supplies, and consumer electronics.
