Texas Instruments TMP401

the tmp401 is a remote temperature sensor monitor with a built- local temperature sensor. the remote temperature sensor diode-connected transistors are typically low-cost npn- or pnp-type transistors or diodes that are an tegral part of microcontrollers microprocessors or fpgas. remote accuracy is 1c for multiple ic manufacturers with no calibration needed. the two-wire serial terface accepts smbus write byte read byte send byte and receive byte commands to program alarm thresholds and to read temperature data. features cluded the tmp401 are series resistance cancellation wide remote temperature measurement range (up to +150c) diode fault detection and temperature alert functions.
