The 9-bit resolution gives 0.5°C per LSB — adequate for over-temperature protection and fan-speed control loops where 1°C granularity is enough. Texas Instruments has marked the LM75CIMX-3/NOPB as obsolete. No official successor is listed. Surface-mount assembly with standard SOIC-8 footprint — no special reflow profile beyond the usual lead-free solder profile. ## Built-in shutdown and programmable limit Features include an output switch (open-drain OS pin), programmable temperature limit, and shutdown mode. The OS pin asserts when the temperature exceeds the programmed threshold — useful as a direct interrupt to a microcontroller or as a hardware thermal shutdown signal without polling the I²C bus. In shutdown mode the device draws minimal current, suiting battery-powered or low-standby-power designs where the sensor is read intermittently.","metaTitle":"TI LM75CIMX-3/NOPB Digital Temp Sensor, I²C, 9-bit, ±2°C","metaDescription":"Texas Instruments LM75CIMX-3/NOPB digital temperature sensor, I²C output, ±2°C accuracy, 3V-5.5V supply, -55°C to +125°C range.
