3 Phase Current Measurements Using a Single Line Resistor on TMS320F240
Texas InstrumentsMost inverter control systems require a knowledge of the phase currents. The simplest method of obtaining these currents is to measure them directly. Depending on the motor winding connections, this r
Single-Supply Operation of Isolation Amplifiers
Texas InstrumentsFor simplicity many systems are designed to operate from a single external power supply. In battery powered systems such as aircraft and automotive it's often a requirement. Isolation amplifiers such as the ISO120 and ISO122 can be easily modified for input side single-supply operation with the addition of an INA105 difference amplifier. With ISO amps it's the isolated input side power supply w
Creating A Delay Buffer on a TMS320C2x EVM
Texas InstrumentsThis document discusses how to implement an audio delay buffer using the TMS320C2x Evaluation Module (EVM). A block diagram of the circuit and a memory map showing how the delay is implemented are included. There is a code listing of the code used for this function.

U-155 Implementing Multi-State Charge Algorithm with the UC3909 Switchmode
Texas InstrumentsThis application note introduces a new dedicated analog controller. The UC3909 Switchmode Lead-Acid Battery Charger IC provides a low-cost solution to battery charging without sacrificing the performance of the system. Also the paper will guide users whose primary expertise is not switch-mode power-supply design in devising a state-of-the-art multi-state battery charger using the new IC. Th
Launchpad-Based MSP430 UART BSL Interface (Rev. A)
Texas InstrumentsThis application report describes the implementation of the low-cost LaunchPad™-based MSP430 universal synchronous receiver/transmitter (UART) bootstrap loader (BSL) interface. The goal of the implementation is to deploy the MSP430 Value Line devices that have less than two serial interface modules as the bridge between the BSL Scripter software tool and the MSP430 target device.
Interoperability of M-LVDS and BusLVDS
Texas InstrumentsM-LVDS is standardized in TIA/EIA-899 to enable interoperability of compliant interface circuits such as the SN65MLVD200 from Texas Instruments. This report compares data sheet specifications and makes a conclusion on the interoperability of the nonstandard BusLVDS (BLVDS) DS92LV010A from National Semiconductor and the SN65MLVD200.
