Serial connection of cells in a battery pack can result in reduced-capacity performance if some of the cells have different capacity or charge levels. The problem is that during charging or discharging of the pack individual cell differences lead to different voltages ineach cell. Since the charger monitors only the summary voltage some cells can be undercharged and others overcharged. Underch

This application report describes how to communicate with the Hercules™ UART bootloader. The UART 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.

Using Standard Power-Over-Ethernet Controllers for High-Powered Devices

This applications report describes the use and benefits of the LP2995 for DDR-DRAM Termination.

This document describes the benefits of the Enhanced Emulation Module (EEM) advanced debugging features that are available in the MSP430™ devices and how they can be used with Code Composer Studio™ IDE(CCS) version 6 software development tool.

The EEM advanced debugging features support both precision analog and full-speed digital debugging. The configuration of the debug environment for maximum control and the use of the embedded trace capability are described. Some techniques that allow rapid development and design-for-testability are demonstrated.

DDR3 memory modules can be populated with EEPROMs that use the Serial Presence Detect memorytechnology. The SPD EEPROM contains information for the memory controller about the memory module.On Registered DIMM (RDIMM) the SPD bytes 65-76 are reserved for register specific content.This application report gives DIMM manufacturers who are using TI registers on their modules arecommendation

Application Note 1155 A Simple Software I2C Routine for the COP8

Analog-to-digital converters can be controlled by a normal I/O port or with the synchronous serial port of the 80x51 microcontrollers. The synchronous serial port is more efficient however there are some pitfalls to be aware of when configuring the 8-pin A/D converters (ADS1286 ADS7816 ADS7817 and ADS7822) from Burr-Brown. This application bulletin describes how to get around these pitfalls an

The INA115 is a precision instrumentation amplifier (IA). Its gain-sense and amplifier output connections are available so that gains can be accurately set using external resistors. By adding switches or a multiplexer you can make a precision programmable-gain IA (PGIA). Using the circuit topology shown in this bulletin the switches are in series with op amp inputs so their resistance does not a

This application report discusses how to design a simple and ultra low-power grip detector BoosterPack for the MSP430 LaunchPad™. The PINOSC feature in every msp430G2xx2 and msp430G2xx3 device makes it possible to eliminate all the external components when implementing a capacitive touch design. All the components used in the grip detector such as capacitive sensors LEDs are all integrate

This application report describes ROM bootloader (RBL) differences between silicon revision 2.1 and 2.3 of the TMS320DM644x Digital Media System-on-Chip (DMSoC).

Practical consideration on choosing a crystal for CDCE(L)9xx family

DC Output Errors in a Fully-Differential Amplifier THS4521 FDA DC Precision

The phase shifted full bridge (PSFB) converter is used for DC-DC conversion in various applications forexample in telecom systems to convert a high voltage bus to an intermediate distribution voltage typicallycloser to 48 V. PSFB stage provides voltage translation as well as isolation from the line voltage sincethis topology includes a transformer.
