As a result of new legal requirements covering the electromagnetic compatibility of electronic equipment users must now address this issue at system conception and when choosing components. This application report is intended to give the development engineer insight into a method of making the measurements that establish those properties of integrated circuits that primarily determine their elect

This application report demonstrates an effective method to interface the ADS1251 and ADS1252 sigma-delta data converters to the MSP430F449 microcontroller. The software for this application report wa

This application report presents a hardware solution for interfacing the TLV1572 10-bit 1.25 MSPS (Mega Samples Per Second) successive low-power analog-to-digital converter (ADC) to the TMS320C203 16-bit fixed-point digital signal processor (DSP). In addition a C-callable interface program is shown which supports the data transfer between ADC and DSP.

Customers can program ten EEPROM registers to optimize the ability of the bq26500/bq26501 to monitor the battery capacity of a given group or type of Li-ion pack cells. This document explains how to obtain the values to be programmed in EEPROM by using information known by the pack/system designers and manufacturers and data collected from packs. HP34401A multimeters and a test setup that includes

This application report describes a real-time high performance simulation environment using the Texas Instruments (TI(TM)) TMS320C40 digital signal processor (DSP). The interactive simulation environment provides a diagnostic system for measuring sampling and diagnosing actual technical processes.The real-time diagnosis of hardware errors reduces the investigative time required to identify e

In USB and isolated low power converter designs-quasi resonant and discontinuous conduction mode flyback converter topologies are a popular choice due to their low parts count and relatively low cost. To reduce the cost even further TI has developed a quasi-resonant/discontinuous current mode flyback controller with primary-side control.

The integrated-circuit (IC) industry is converting to nickel/palladium (Ni/Pd)-finished leadframes for assembly of ICs. To dateTexas Instruments (TI) has over 20 billion Ni/Pd ICs in the field.Users of IC components need to know the maximum length of time that components can be stored before being soldered. The goal of this study was to predict shelf life of Ni/Pd-finished components by expos

This application report describes how to communicate with the Hercules™ serial peripheral interface (SPI) bootloader. The SPI bootloader is a small piece of code that can be programmed at the beginning of Flash to act as an application loader as well as an update mechanism for applications running on a Hercules Cortex™-R4 based TMS570LS31x microcontroller.

This application report discusses the process to replace the CLC014 adaptive cable equalizer with the LMH0074 adaptive cable equalizer.

This application report contains implementation instructions for the DDR2 interface contained on the TMS320DM643x digital signal processor (DSP) device. The approach to specifying interface timing for the DDR2 interface is quite different than on previous devices.

The previous approach specified device timing in terms of data sheet specifications and simulation models. The system designer was

COP8 Instruction Set Performance Evaluation

The ADS7800 12 bit Sampling analog-to-digital-converter is designed to operate with bipolar inputs of ±5V or ±10V. With the addition of an external amplifier the ADS7800 can be used for 10V or 20V unipolar inputs. Four unipolar input options are shown in this Bulletin.

This application report explains how to configure an application based on pure software libraries and routines and how to properly use the provided ROM contents for the TMS320C672x DSP generation of devices. Several software examples are provided explaining the process in progressive steps.

The maximum input voltage rating of the bq243xx family of ICs is 30 V. However some customers like to perform a 24-V hot plug-in transient test to prove its high-voltage capability and reliability from a system level. It is important for system designers to properly design the charging system with correct system-level protections. Usually a TVS (transient voltage suppression) Zener diode is used

This application report presents practical single-cell battery discharge characteristics in real-world application and primarily focuses on the varying internal impedance of a battery and how that affects the battery terminal voltage.

This application report discusses the effect of heavy loads on the accuracy and linearity of operationalamplifier circuits.

The UC3625 brushless DC-motor control IC incorporates many useful features that greatly simplify the design of low-cost and reliable brushless DC-motor drive systems. Although the controller IC is designed for ease of circuit implementation a few precautions are necessary to insure proper operation. This design note discusses a few situations in which the IC may not operate correctly if suitable

Use of 4-mA to 20-mA (4-20 mA) current loops has become the standard in the process-control industry due to their increased resistance to noise compared to voltage-modulated signals. TI digital signal processors (DSPs) increasingly are becoming the standard for microcontrollers in a control application. Therefore an opportunity exists to connect the many sensors and electromechanical devices on t
