Key Features
- 12-bit resolution providing 0.0625°C temperature step, enabling high-accuracy thermal monitoring in tight closed-loop control loops without external ADCs
- I2C/SMBus interface with up to 4 user-selectable addresses, allowing up to 4 TMP100-EP sensors on the same 2-wire bus for multi-zone thermal management
- Enhanced Product (EP) qualification supporting extended temperature operation from -40°C to 125°C with tighter parametric limits for industrial and defense applications
Applications
The TMP100-EP is designed for thermal management in industrial control systems, server boards, and telecom infrastructure where continuous temperature monitoring from -40°C to 125°C is required with I2C readout. Its 6-pin SOT-23 package and 2-wire interface make it easy to deploy in space-constrained embedded systems alongside processors and power regulators. The Enhanced Product screening ensures long-term availability and parametric stability for extended-lifecycle programs in avionics and medical instrumentation.

Frequently Asked Questions
What temperature range and resolution does the TMP100-EP support?
The TMP100-EP measures temperatures from -40°C to 125°C with a programmable resolution of 9, 10, 11, or 12 bits, achieving up to 0.0625°C per LSB at 12-bit mode. This makes it suitable for precise thermal monitoring in industrial servers and motor drive thermal protection circuits.
How many TMP100-EP sensors can share the same I2C bus, and what interface does it use?
The TMP100-EP communicates over a standard 2-wire I2C/SMBus interface at up to 400 kHz (Fast Mode) and provides up to 4 hardware-selectable I2C addresses via the ADD0 and ADD1 pins, allowing 4 devices to coexist on one bus for multi-zone thermal management in power supply and rack server designs.
What makes TMP100-EP an Enhanced Product and why does it matter for procurement?
The TMP100-EP Enhanced Product designation means Texas Instruments commits to a minimum 10-year supply continuity, wider parametric screening, and accelerated-life qualification compared to the standard TMP100. This matters for defense, avionics, and medical programs that require long production horizons and tighter guaranteed accuracy across the -40°C to 125°C range.
What package does TMP100-EP come in, and is it suitable for high-density designs?
The TMP100-EP is housed in a 6-pin SOT-23 package measuring approximately 2.9x1.6 mm, one of the smallest surface-mount footprints available for a digital temperature sensor with I2C output. This makes it ideal for embedding next to FPGAs, DSPs, or DC-DC converters on boards where thermal sensor placement space is limited to under 5 mm2.
