Here’s a video tutorial from Texas Instruments describing basic sensored BLDC motor operation. Michael Firth, Motor Driver marketing manager, discusses the basic operation of a BLDC motor.
This video by Robert Kollman, TI senior applications engineer, discusses how to use a two section filter for a low noise power supply.
Here is a video from Texas Instruments describing how to measure stability when testing power supplies.
Here is a video from Texas Instruments describing how to test DC-DC power supplies. Measurement of ripple and transient noise of switching power supplies is described in detail.
A video tutorial on the benefits and pitfalls of using aluminum electrolytic capacitors. Learn how these capacitors degrade, and how their life cycle is proportional to the stresses you put them through.
Texas Instruments goes over regulator output-voltage accuracy, warning that feedback resistor tolerances have a high impact on the output accuracy and should be chosen with care.
As with all electronics components capacitors can never be ideal, there are always parasitic components that have to be considered as well. With capacitors the most prominent parasitics are Equivalent series resistance (ESR), and Equivalent series inductance (ESl). The video … Read more
Here’s is a video from Texas Instruments describing the inner workings of delta-sigma analog to digital converters. The DS ADC is broken down into it’s basic parts. The delta-sigma modulator and digital decimating filter are then discussed. Delta-sigma converters are … Read more
Texas Instruments describes bootloaders and what they are all about. A bootloader is a piece of code that allows new firmware to be loaded into a microcontroller without a dedicated programmer. All of our projects use a bootloader so you … Read more
Here is a video from Texas Instruments describing the differences in motor pre-drivers vs integrated drivers. Pre-drivers have all the control circuitry but the FETs are external, while in integrated drivers everything is on one IC. Because pre-drivers use external … Read more
Mouser is giving away the Texas Instruments FRAM MCUs for Dummies book. Hand over your personal details to Mouser if you’re willing, and they’ll send you the book. Could be fun. Via the forum. Thanks Chuckt!
Texas instruments released the Power Management reference design library. It’s filled with schematics, design notes, gerber files, and any technical document you might need to get over 300 reference designs up and running. Texas Instruments PowerLab™ Power Management Reference Design … Read more
This app note from Texas Instruments focuses on understanding and interpreting datasheets for logic ICs. To assist component and system-design engineers in selecting Texas Instruments (TI) standard-logic products, this application report is a synopsis of the information available from a … Read more
Here is Texas Instrument’s application note on Ball Grid Array IC packages. It provides general information about BGAs, and the many versions of the same. Leaders in the consumer electronics industry will be determined by their ability to deliver increasingly … Read more
Adding transient suppressors to USB devices [PDF!] can help prevent damage from static discharge. This is important because USB devices are handled without protection, carried in pockets, tossed in bags, etc. Because frequent human interaction with the USB system occurs … Read more
Here is an app note from Texas Instruments describing how to implement multiple time-base outputs from a single timer module on a MSP430 microcontroller. The timer modules on MSP430™ ultra-low power microcontrollers often base several different outputs off of a … Read more
An MSP430-based USB Li-Ion battery charger with a fuel gauge: The example cases discussed in this application report provide a basic understanding of what needs to be done at production, as well as on the application level, to achieve the … Read more
Here is an app note from Texas Instruments describing how to use their LMP8646 ‘shunt’ current monitor as a current limiter on linear, and switching power supplies. The LMP8646 is a precision current limiter used to improve the current limit … Read more
It can be a challenge to interface 5volt stuff with modern 3.3volt microcontrollers like an ARM or MSP430. This app note covers several circuits for voltage translation on input, output, and bidirectional pins. The interfacing of the 3-V MSP430x1xx and … Read more
