Microchip | TC77-3.3MCTTR

Microchip Technology is a leading innovator and supplier of high performance and high quality embedded solutions and microcontrollers; related non-volatile memory products; and a broad analog product line focusing on power management, thermal management, linear and mixed-signal solutions.

Temperature sensing is critical to a growing number of consumer, automotive, and industrial applications. Microchip’s digital temperature sensors are ideal choice for implementing temperature system management schemes in a variety of applications.

TC77 - Thermal Sensor with SPI™ Interface

TC77 is a serially accessible digital temperature sensor capable of reading temperatures from -55°C to +125°C and particularly suited for small form-factor applications.

Temperature data is converted from the internal thermal sensing element and made available at anytime as a 13-bit two’s compliment digital word. The TC77 offers a temperature accuracy of ±1.0°C (max.) over the temperature range of +25°C to +65°C.

When operating, the TC77 consumes only 250 μA (typ.). The TC77’s Configuration register can be used to activate the low power Shutdown mode, which has a current consumption of only 0.1 μA (typ.).

Communication with the TC77 is accomplished via a SPI and MICROWIRE compatible interface. It has a 12-bit plus sign temperature resolution of 0.0625°C per Least Significant Bit (LSb).

The TC77-3.3MCTTR is a SOT-23 Thermal Sensor with SPI™ Interface with accuracy optimized for 3.3V.
