Part Details for TRS3232E by Texas Instruments

This reference design implements Class 0.5 single-phase energy measurement using standalone multi-channel analog-to-digital converters (ADC) to sample a shunt current sensor. With the combination of the shunt sensor and a compact magnetically immune power supply: the design provides protection against magnetic tampering attacks. The design also provides the capability to detect potential tampering from neutral line disconnection. The combination of a high-performance ARM Cortex-M4 MCU to execute the metrology calculations and 8-kHz sampling rate allows the addition of power quality functions: such as individual harmonic analysis.

This reference design implements Class 0.1 split-phase energy measurement using high-performance: multi-channel analog-to-digital converters (ADC). The independent ADC samples the output of current transformers (CT) at 8 kHz to measure the current and voltage of each leg of the AC mains. The reference design can achieve high accuracy across a wide input current range (0.05 – 100 amps) and supports high sampling frequencies necessary for advanced power quality features such as individual harmonic analysis. Using an independent ADC to sample the CT output provides designers greater flexibility in the choice of metrology microcontrollers when compared to integrated SoCs and dedicated application-specific products. The reference design uses a SimpleLink™ ARM Cortex-M4 host microcontroller to calculate energy measurement parameters.  This design can also use an ADC sample rate of 32 ksps by only enabling a subset of the full energy measurement parameters.

Use this reference design to quickly establish a wireless network that connects various types of sensors for condition monitoring directly to the Cloud. Condition Monitoring is based on a regular or permanent recording of the machine condition which is necessary for predictive maintenance. Inputs such as RS-232: RS-485: IO-Link or resistance temperature detectors (RTDs) are included in the design to monitor different sensors and machines.

This reference design is for a multiparameter front end of a patient monitor that measures vital sign parameters like ECG: heart rate: SpO2 and respiration.it uses biosensing front end integrated circuits like the AFE4403 and ADS1292R devices: to measure these parameters. It also uses three TMP117 sensors to accurately measure skin temperature. This design can interface with the pace detection module to detect the pace pulse. The design also uses an isolated UART connection to transfer data to a computer. The entire front end subsytem runs on a rechargeable 3.7V li ion battery.
