Current measurements are used in electronic systems to provide feedback verifying operation is within acceptable margins and to detect potential fault conditions. Analyzing a system’s current level can diagnose unintended or unexpected operating modes allowing for adjustments to be made to improve reliability or to protect the system components from damage.

Power demands of today's modern systems have created the need for sensors to shut down when not in use. Through the strategic placement of TI's FemtoFET product line, significant power savings can be realized for several parts in the TI current sensing product line.

This application report discusses digital filters which are a ubiquitous feature in delta-sigma analog to digital converters (ADCs). Digital low-pass filters are essential to the functionality of a delta-sigma ADC, which relies on oversampling and noise shaping to push quantization noise out of band. There are variations between the types of digital filters used in delta-sigma ADCs that provide various benefits and drawbacks that orient them to different applications. The types of filters and the tradeoffs between them are discussed in this report.

The ability to dynamically control current in an inductive load system is very important for stepper motor designs where different levels of torque control are desired. This adjustment feature can also be used to improve system efficiency by reducing the motor current in low-load situations, achieving a longer battery life.

This application report is provided as a supplement to the data sheet for the DRV8884, DRV8885, DRV8886 and DRV8886AT motor drivers. The goal of this document is to show how to achieve accurate current regulation in normal and low-power modes using different methods. This document also describes different sources of error in these configurations, how to minimize these errors, and the key factors to consider when doing a design.

Operational amplifiers (op amps) with electromagnetic interference (EMI) filters can reduce significant errors. These types of errors are not always obvious to the system designers. They often impact the signal chain, in particular the analog-to-digital converter in the form of a loss of digital counts.

The TUSB546A-DCI is a linear redriver that supports both USB3.1 Gen1 and DisplayPort 1.4 over a USB Type-C interface. Even though the TUSB546A-DCI was released for the DisplayPort Alternate mode, the TUSB546A-DCI can also be used as a redriver in a USB-C HDMI Alternate mode source application. This document is intended to describe how to use the TUSB546A-DCI in a HDMI Type-C source application. The information in this document can also be applied to the TUSB546-DCI, TUSB1046-DCI, and TUSB1046A-DCI. For the remainder of the document TUSBx46 is used to describe all of these parts

This application note introduces features and performance of TI’s first Network Synchronizer Clock device, LMK05028. The application note highlights the device's unique 3-loop architecture, Hitless Switching with Phase Cancellation, 1 PPS Phase Lock, Zero Delay Mode, and Robust Reference Detector, and discusses their value adds in several applications, including wired communications (Switches, Routers and Optical Transport Networks), wireless communication (Base Band Unit), and industrial applications, such as smart grids, medical imaging, and broadcast video. In these applications, the LMK05028 operates as a high-performance clock generator and jitter cleaner with Programmable Loop Bandwidth, while also offering network synchronization with support for Synchronous Ethernet (SyncE) and IEEE 1588.

CAN interface has been a very popular serial communication standard in the industry due to its excellent prioritization and arbitration capabilities. In systems with different voltage domains, isolation is typically used to protect the low voltage side from the high voltage side in case of any faults. Isolation also breaks any ground loops allowing only the desired signals to be transmitted, thereby improving signal quality.

Isolated CAN is used for communication with the microcontroller in a wide range of applications such as solar inverters, circuit breakers, motor drives, PLC communication modules, telecom rectifiers, elevators, HVACs and EV charging infrastructures.

In a RF system having the best possible range is important in many cases. There are many factors that can cause poor range. This application report provides a step-by-step guide on which parts of the design could cause shorter range than desired.

Residential smart meters are used for billing of electricity, gas, water, and heat. The technological advancements in these smart meters are being driven by the demand from utility companies to create a smarter and more efficient grid aimed at reducing non-revenue losses. More sensors are being added to collect more data about the status of the grid including pressure, temperature, etc. There is also a growing trend to incorporate higher precision measurements with newer technologies, such as ultrasonic flow measurements, which often end up adding to the overall complexity, reliability, and power consumption. These meters are also often part of radio-frequency (RF) communication networks that can draw a variable amount of power from the system depending on the required output power of their signal.
