I2C interface (SMBusTM compatible)
The TMP9R01-SEP device is a radiation-tolerant, high-accuracy, low-power remote and local temperature sensor that integrates a 12‑bit ADC, bias currents, and on‑chip calibration circuitry for temperature sensing. This device is available in a 10-pin VSSOP plastic-encapsulated package. By forcing a bias current through an external BJT transistor, or the diode/junction integrated in an FPGA, ADC, or ASIC, the device digitizes the resulting ΔVBE and directly reports with a 0.0625°C temperature resolution. The second on‑chip sensor measures local temperature, enabling on-board temperature sensing.
The TMP9R01-SEP device incorporates multiple calibration and protection features, including series resistance cancellation, programmable non‑ideality factor (η-Factor), offset correction, and programmable digital filter. The user can set high and low temperature limits that drive the ALERT output for over- and under- temperature thermal protection. The I2C/SMBus serial interface accepts up to nine different pin-programmable addresses on the same I2C bus. The TMP9R01-SEP device is also available in a QMLV (TMP461-SP) and QMLP (TMP9R01-SP, prerelease) versions, with higher radiation specs.
The TMP9R01-SEP device is ideal for multi‑location spacecraft housekeeping, satellite telemetry, avionics, and other high‑reliability industrial or medical designs that require precise temperature sensing and radiation tolerance.
