TCN75 Overview
Key Features
- s s s s s s s s s s Solid State Temperature Sensing; 2°C Accuracy (Typ.) Operates from – 55°C to +125°C Operating Range
- 250µA (Typ.) Operating 1µA (Typ.) Shutdown Mode 8-Pin Plastic DIP, SOIC, and MSOP Packaging perature exceeds a user-programmed setpoint
- Hysteresis is also programmable
- The INT/CMPTR output is programmable as either a simple comparator for thermostat operation or as a temperature event interrupt
- Communication with the TCN75 is accomplished via a two-wire bus that is compatible with industry standard protocols
- This permits reading the current temperature, programming the setpoint and hysteresis, and configuring the device
- The TCN75 powers up in Comparator Mode with a default setpoint of 80°C with 5°C hysteresis
- Defaults allow independent operation as a stand-alone thermostat
- A shutdown command may be sent via the 2-wire bus to activate the low-power standby mode
- Address selection inputs allow up to eight TCN75's to share the same 2-wire bus for multi-zone monitoring
