How to balance efficiency and settling time with highly integrated DACs

In my first post , I talked about the need for modular, flexible and smart design in analog output modules and explored methods for improving efficiency in a typical high-side voltage-to-current converter used to drive 4-20mA outputs. Figure 1 shows an implementation that involves a buck/boost converter in a simple feedback network to supply just the necessary power to the load. While this implementation makes 4-20mA...

Zero out your system error with zero drift, zero crossover and zero hassle

This post is co-authored by Richard Barthel and Errol Leon . In applications such as position sensors, data-acquisition systems and resistance temperature detectors (RTDs), it is important to design with high precision in mind. In many cases, designing with precision integrated circuits (ICs) reduces signal-chain complexity, lowers the external component count, and minimizes board space and bill of materials (BOM)...

From the Experts: Perform cyclic redundancy checking using linker-generated CRC tables

To verify code and/or data integrity, TI’s microcontroller (MCU) Code-Generation Tools (CGTs), including the C2000™ MCU CGT, the MSP430™ MCU CGT and the TI ARM CGT, support cyclic redundancy checking (CRC). This method can greatly enhance the performance of your embedded design and is easy to use, once you understand the basics of how CRC works. The focus of this blog post will be CRC with the C2000...

Extend battery life with a LDO, a voltage supervisor and a FET

Extended battery life is a common design requirement across a variety of applications. Whether it’s for toys or water meters, designers have various techniques at their disposal to improve battery life. In this post, I will illustrate one such technique that involves strategically bypassing a low dropout linear regulator (LDO). Generating the rail Using an LDO is a common way to generate a regulated voltage...

Don’t let your battery drain on the shelf – use ship mode

Don’t let your battery drain on the shelf – use ship mode You’ve done it; your battery-powered design is complete: a new wearable for the consumer electronics market. You’re excited, and you want your consumers to feel that same excitement when they open the box and turn the device on. But how do you make sure that happens? A Christmas present bought in advance can be sitting in wrapping paper...

Make your power bank more reliable with output short-circuit protection

Lithium ion (Li-Ion) or lithium polymer (LiPo) batteries are key components in some portable systems, especially power banks. But on rare occasions, these batteries have the potential risk of catching on fire or even exploding in short-circuit, overvoltage or high-temperature conditions. An increasing number of such incidences are occurring even today. To hel p safeguard consumers against these conditions, Underwriters...

A mini data concentrator for the smart grid

Infrastructure equipment such as data concentrators and broadband backhaul routers represent a large portion of the cost of electric utilities’ advanced metering infrastructure (AMI) networks. Reducing the required capex by optimizing infrastructure deployments helps improve overall project’s return on investment. Utilities deploying AMI networks with power line communications (PLC) need to determine the...

Multiplexers: not so simple

It’s simple to design a multiplexer (or mux for short) into a signal chain, right? After all, the device simply funnels multiple signals into a data converter. In reality, a mux can significantly impact the performance of a signal chain in a variety of ways. For example, the on-capacitance can cause crosstalk between channels. Signal- and temperature-dependent variations in the on-resistance can introduce signal...

How to build a monitor and control solution for voltage regulators

In my last post , I talked about how to use a precision digital-to-analog converter (DAC) to margin a voltage regulator like a low-dropout regulator (LDO) or switch mode power supply (SMPS), providing the ability to either precisely tune the output or allow it to swing over a wide range of voltages. In this post, I will expand upon that idea to build a closed-loop system that, alongside the compute power of a microprocessor...
