The UCC3806 is a pin-for-pin-compatible BiCMOS replacement for the UC3846 and UC3856. However this design note explains how some functions in the UCC3806 are programmed differently. In particular the CUR LIM ADJ pin programs the maximum peak current for the current-sense amplifier. This function is completely compatible with that of previous ICs. The second function on this pin is the latch/non-

The OMAP5910 is a true system-on-a-chip device which consists of ARM925T MPU and C55X DSP cores. The device has many advanced power management modes that enable system designers to develop a very low-power multimedia communication device. This application note shows low-power design techniques and outlines the steps required to put the OMAP™ device in the lowest power consumption mode and

This application report describes methods for measuring code execution time of TMS470 and TMS570 microcontrollers. Besides the typical pin toggle approach, where the duration between two pin toggles i

This application report outlines the implementation of a CPE remote management scheme using the clear EOC Channel. The capabilities of the Clear EOC Channel are discussed for G.dmt different framing mode as well as ADSL2. This application report is meant to be used to provide a basic understanding of the Clear EOC channel and how it might be used for ADSL CPE remote management.

The inter-integrated circuit (I2C) is a multi-master multi-slave single-ended bus that is typically used forattaching lower speed peripheral ICs to processors and microcontrollers. The type of slave devices range from non-volatile memory to data-acquisition devices like analog-to-digital converters (ADC) sensors and so forth. This application report demonstrates how to use the feature rich I

With ever increasing speeds of DSP devices such as the 'C5x and the increasing demand for reduced form factors as in HDD applications there is a need for integrating the program memory into the DSP device. For volume production where the program code has been fully debugged and changes are not foreseen then masked ROM is appropriate. However for prototyping and preproduction evaluation a p

Negative Buck Switching Regulator (using LM258x)

The switch-mode power supply primary current is often sensed using a power resistor. Using an op amp to amplify the current-sense signal can reduce cost and improve noise performance and efficiency. T

This application note discusses the operation and compensation of linear regulators.

This application report reviews several different types of bridge sensors including characteristics of each type and discusses the key parameters of delta-sigma (ΔΣ) analog-to-digital converters (ADCs) at the system level. Additionally the parameters of a ΔΣ ADC are considered for use in common bridge sensor applications

This application report explains the implementation of an Attitude and Heading Reference System (AHRS) using the ultra-low-power MSP430F5xx microcontroller a magnetometer a gyroscope and an accelerometer on all three axes. The calibration of the sensors is key to the accuracy of the algorithm therefore the sensors’ output must be calibrated before being input to the Direction Cosine Matrix (

AN071 -- CC2430 to CC2530 Migration Guide

In any digitizing system, antialiasing and anti-imaging filters are used to prevent the signal frequencies from "folding back" around the sample frequency and causing false (or alias) signals from app

This document describes the features of the on-chip bootloader provided with the TMS320VC5510 Digital Signal Processor (DSP). Included are descriptions of each of the available boot modes and any interfacing requirements associated with them instructions on generating the boot table and information on migration from the prototype (TMX320VC5510 revision 1.x) to the production (TMS320VC5510) boot

Battery charger ICs base their full charge termination on either peak voltage detect (PVD/-dV) for nickel chemistries (bq2000, bq2002, and bq2004) or current taper for Li-ion batteries (bq24010, bq240

Predictive Gate Drive™ is a novel digital control-driven technique that optimizes MOSFET turn-on and turn-off delays in synchronous rectifiers. It uses a closed loop feedback system to detect body-diode conduction and continuously adjusts dead-time delays to minimize the conduction time interval. Depending upon operating frequency and output voltage the Predictive Gate Drive™ control
