In Li-ion battery pack design short-circuit protection should be given sufficient emphasis to ensure that even if an external pack short does occur it is benign. Properly designed battery fuel gauge solutions using the bq29330 analog front-end (AFE) protector and bq20z70 bq20z75 bq20z90 and bq20z95 fuel gauge ICs not only safeguards the battery but also ensures a full recovery of functionali

Described in this document are application ideas and reference designs for the TLC5940 LED driver. The following application example shows the building of a basic module of an LED display system using a cascading connection on n TLC5940 devices connected to a controller. The reference design implements three TLC5940 devices to drive 16 LEDs.

Decoupling the power supply pins of high-speed operational amplifier circuits is critical to their operation. Decoupling is also one of the least understood topics in engineering. It is seldom given the time or care required yet it is relatively simple. This document will explain the pitfalls in decoupling and offer some correct techniques.

Moisture Sensitive Classification of Flange Mounted Packages at Texas Instruments

The last year has seen the introduction of silicon temperature sensors in revolutionary small packagesideal for portable systems. This application report discusses trade-offs in accuracy as well as how tochoose between thermistors and analog output IC temperature sensors.

This application report discusses using the Texas Instruments LM25066 in an Intel™ Node Manager 2.0 System.

Caller ID is a method of transmitting the telephone number and/or name of the caller to the subscriber via a burst of V23 or BEL202 data during the ringing phase of a telephone call. Various methods of signaling the start of this message are used in different countries and this report attempts to identify a near universal core routine for handling the messages within the DSP environment. ADSI is a

Using External Soft Start Circuit for UCC2806x

The steady increase in memory densities used in microprocessor based systems has stretched functional test times. The boundary scan standard IEEE 1149.1 offers a solution to the problem of testing static memory by supplying the access needed to control built-in-self-test (BIST) functions. This document describes generation patterns using parallel signature analysis (PSA) and BIST generated wavef

In an increasingly wireless world electrostatic discharge and electromagnetic interference are both potential issues for portable battery packs. This application report discusses the causes of ESD and EMI issues in battery pack designs and offers solutions for mitigation.

DRV2603, DRV2604, DRV2605 Benefits of LRA Auto-Resonance Tracking

This document describes how to interface the multichannel buffered serial port (McBSP) in the TMS320C6000? digital signal processor (DSP) to a voice band audio processor (VBAP). The VBAP under discussion is the TI TLV320AC56 3V 2.048 MHz audio processor which is a m-law companding device. The interface is also applicable to TI?s TLV320AC57 an A-law companding audio processor.The highly

The DAC8534 is a quad-channel, low-power, 16-bit, serial digital-to-analog converter. This application report presents a method for interfacing the DAC8534 to the TMS320C6x-series DSKs using McBSP1 an

This technical brief is an overview of the low power architectural features and design considerations of the TMS320LC54x DSP (Digital Signal Processor) family. For those with a deeper interest in low-power DSP design this technical brief also provides an overview of a more detailed application brief titled Calculation of TMS320C54x Power Dissipation TI literature number SPRA164. The audience

This application report reviews the design steps used in the evaluation module (EVM) UCC25230EVM-754. The EVM helps evaluate the UCC25230 pulse-width modulation (PWM) controller in a forwardflyback or Flybuck™ dc-dc converter topology for a 48-V telecom bias supply. The EVM is a dual-output converter with 1500-VDC isolation between the two outputs. Each output is typically rated as 12 V and 65 m
