TCN75-3.3MOA Product Details

TCN75-3.3MOA is a serially programmable temperature sensor that notifies the host controller when ambient temperature 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 TCN75-3.3MOA 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 TCN75-3.3MOA 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 shut-down 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.All registers can be read by the host and the INT/CMPTR output's polarity is user programmable. Both polled and interrupt driven systems are easily accommodated. Small physical size, low installed cost and ease of use make the TCN75-3.3MOA an ideal choice for implementing sophisticated system management schemes.
