Shenzhen Mingjiada Electronics Co., Ltd. a globally renowned electronic component recycler, consistently purchases Texas Instruments (TI) evaluation boards and development kits in full series for cash worldwide. Among these, the TMP451EVM Remote Temperature Sensor Evaluation Module is one of the company's key high-value acquisition targets.
Overview
The TMP451EVM is an evaluation module designed for comprehensive assessment of the 1.8V remote temperature sensor TMP451. The TMP451 features the capability to measure both remote and on-chip temperatures. This integrated circuit delivers temperature measurements with 1°C accuracy and incorporates ALERT and THERM functions, making it suitable for mobile devices and low-cost applications. The evaluation module includes a USB interface, microcontroller, TMP451 device, remote bipolar transistor, and supporting circuitry.
Features
• Supports comprehensive evaluation of the TMP451
• Programmable non-ideal coefficients
• Series resistance compensation
• 12-bit resolution
Key Technical Features of the TMP451 Chip
• Dual-channel temperature measurement: Supports simultaneous remote temperature (via external transistor connected to D+/D-) and on-chip local temperature measurement, meeting multi-point temperature sensing requirements for processors, FPGAs, etc.
• High-precision performance: Local and remote sensor accuracy reaches ±1°C (maximum) within typical operating range, with 0.0625°C resolution using 12-bit digital encoding
• Wide voltage range: 1.7V to 3.6V supply and logic voltage range, supporting 1.8V low-power interfaces for modern low-voltage digital systems
• Low-power design: Operating current of only 27μA, shutdown current as low as 3μA, suitable for battery-powered and energy-saving applications
• Advanced calibration features:
• Series resistance compensation: Eliminates the impact of PCB trace resistance on measurement accuracy
• N-factor and offset correction: Compensates for transistor nonlinearity to enhance measurement precision
• Programmable digital filter: Suppresses noise interference to enhance system immunity
• Fault detection capability: Integrated diode failure detection ensures reliable remote sensor connections
• Standard communication interface: Supports SMBus™/I²C two-wire serial interface for seamless communication with host MCUs
