This application report presents a solution for the control of brushless DC motors using theTMS320F2803x microcontrollers. TMS320F280x devices are part of the C2000™ family ofmicrocontrollers that enable the cost-effective design of intelligent controllers for three-phase motors byreducing the system components and increasing efficiency. Using these devices it is possible to realizefar mo

Block floating-point (BFP) implementation provides an innovative method of floating-point emulation. This application report implements the BFP algorithm for the Fast Fourier Transform (FFT) algorithm on a Texas Instruments (TI) TMS320C54x DSP by taking advantage of the exponent encoder and normalization units on the DSP. The BFP algorithm as it applies to the FFT allows fractional signal gain adj

The PGA450-Q1 device must be optimized and fine-tuned for each particular application. All supporting materials provided by TI for the PGA450-Q1 have been optimized for Texas Instruments' lab-bench setup. The PGA450-Q1 device is not ensured to perform identically in an end-user’s test environment because of varying environmental factors.
These factors include temperature humidity air p

In recent years Passive Go (PG) systems for motorcycles have been developed that have been copied from automotive Passive Entry and Passive Start (PEPS) systems. But for bikes with no requirement to unlock doors or roll down windows at a distance such systems are over-designed with their UHF uplinks. The MCU RF group at Texas Instruments has developed a complete low-frequency approach to this pr

The switcher with integrated FETs (SWIFT?) TPS5461x family of internally compensated synchronous buck regulators offers a quick and easy solution to many power supply applications. These devices require a minimum of six additional components. The design procedure is simple and can be accomplished with the five basic steps outlined in this application report.

This design notes shows the hot swap designer how to control a ?5V rail using a UCC3919 Hot Swap Power Manager. This technique could also be applied using other positive Hot Swap Power Managers. Two c

The ISO120/121/122 isolation amplifiers (ISO amps) have a small (10-20mVp-p typ) residual demodulator ripple at the output. A simple filter can be added to eliminate the output ripple without decreasing the 50kHz signal bandwidth of the ISO amp.

This power supply was designed to power the transceivers in the Xilinx? Virtex?-5 LXT and FXT platforms.

This application brief takes the low-cost heart-rate monitor solution (based on the LaunchPad with MSP430G2452) one step further by adding multiple tasks and a robust software framework on the MSPEXP430F5438 Experimenter Board. The uC/OS-II Real Time Kernel from Micrium handles the execution of multiple tasks in order of their priorities: heart-rate monitoring heart-beat audio output beats-per-m

Application Note 807 Reflections: Computations and Waveforms

Although it is commonly stated that isolating interfaces removes ground potential differences (GPD) and ground loops it is also often unknown how and where these GPDs originate what their waveforms or frequency content is and why ground loops can represent a real nuisance.This application report explains how electrical installation systems wired correctly (or incorrectly) in combination w
