Microchip | TCN75-3.3MUA

The TCN75-3.3MUA is a part of TCN75 Series Temperature Sensors.It can sustain a standard temperature ranging from -55 to +125°C. It comes in 8 pin MSOP package.

TCN75 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.
