Configuring PWM Outputs of TMS320F240 With Dead Band for Different Power Devices
Texas InstrumentsThe DSP controller TMS320F240 has a programmable dead band generator to insert a dead band between two PWM outputs. The polarity of PWM channels (active high or active low) can be controlled using the ACTR register. The appropriate dead band between two PWM outputs can be inserted using the DBTCON register. This document discribes how to configure the PWM outputs with dead band for different powe
Internetworking The SN74ABT3614 (Rev. A)
Texas InstrumentsThe SN74ABT3614 is a clocked FIFO memory with enhanced features such as byte-swapping parity-generation and parity-checking. The four sections of this document describe the architectural implementation of these features the Port-B configurations for bus-matching and byte-swapping the internal register specifics for parity-generation and parity checking and an internetworking application using
Using ADS8410/13 in Cascade Mode
Texas InstrumentsMany applications require multiple analog-to-digital converters (ADC) in a system. Cascading multiple ADCs enables the use of a single data receiver or a small FPGA. This offers lower power consumption and independent ADC usage. This application report describes how multiple ADCs (ADS8410/13) work in a cascade mode. The ADS8410/13 integrated circuit offers a high-speed (200 Mbps) LVDS serial inter
AN-233 The A/D Easily Allows Many Unusual Applications (Rev. B)
Texas InstrumentsTwo design features of the Texas Instruments ADC0801 series of A/D converters provide for easysolutions to many system design problems. The combination of differential analog voltage inputs and avoltage reference input that can range from near zero to 5VDC are key to these application advantages.
TCI66616 to TCI6618 Migration Guide (Rev. A)
Texas InstrumentsThis document describes the main differences between the TMS320TCI6616 and TMS320TCI6618 devices and how to migrate the TMS320TCI6616-based system design to the TMS320TCI6618 design.
Optimizing Control Algorithms on the 'C5x
Texas InstrumentsIn many control algorithms, a value that resides in the 32-bit accumulator must either be stored to a 16-bit memory location or to a peripheral device that may be less than or equal to 16 bits in reso
Highly Integrated PMIC for Powering the SamsungS3C6400-533MHz
Texas InstrumentsThis design was created to help those needing to power the Samsung S3C6400-533MHz and doing so by implementing a highly integrated and efficient design using the TPS650245 power management unit.

Implementing DDR2 PCB Layout on the DM4xx DMSoC (Rev. B)
Texas InstrumentsThis document contains implementation instructions for the DDR2 interface contained on the TMS320DM4xx Digital Media System-on-Chip (DMSoC) 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 customer was required to
Interfacing the TLC2552 and TLV2542 to the MSP430F149
Texas InstrumentsThis application note discusses the features of the TLC2552 and TLV2542 ADC. An SPI interface code example for the MSP430F149 to the TLC2552 ADC, and for the MSP430F149 to the TLV2542 ADC, are also pr
Reducing Precharge Phase Region for bq24650
Texas InstrumentsThe bq24650 is a battery charger operates in three phases: precharge phase, fast-charge current regulation, and fast-charge voltage regulation. In many applications, a long precharge region is not req
Op Amp Performance Analysis
Texas InstrumentsThis bulletin reflects the analysis power gained through knowledge of an op amp circuit's feedback factor. Feedback dictates the performance of an op amp both in function and in quality. The major specifications of the amplifier descibe an open-loop device awaiting feedback direction of the end circuit's function. Just how well the amplifier performs the function reflects through the feedback inte
Fast Cell Balancing Using External MOSFET (Rev. A)
Texas InstrumentsThe need for cell balancing comes from the fact that cell-to-cell differences in self-discharge capacity and impedance can lead to different charge states among the cells. However the charger terminates the charge based on the summed voltage only which may leave some cells undercharged and others overcharged. To remedy this imbalance and to achieve the goal of having all cells reaching 100% st
Using CDC2509A/CDC2510A PLL With Spread Spectrum Clocking (SSC)
