MICROCHIPTC74A4-3.3VCTTRTemperature Sensor, Digital Output, Surface Mount, I2C, SMBus, ±3°C
The Microchip tiny serial digital temperature sensor particularly suited for low cost and small form-factor applications. Temperature data is converted from the on-board thermal sensing element and made available as an 8-bit digital word. Communication with the this IC is accomplished via a simple 2-wire SMBus/I2C™-compatible serial port. This bus also can be used to implement multi-drop/multi-zone monitoring. The SHDN bit in the CONFIG register can be used to activate the low-power Standby mode. Small size, low installed cost and ease of use make the it an ideal choice for implementing thermal management in a variety of systems.
