This application report explains the similarities and differences between the Texas Instruments TPS2205/TPS2211 PC Card Power Interface Switches and the Micrel MIC2563A/MIC2562A devices. The report provides a detailed examination of the parallel interfaces employed by each device. The interface to the Ricoh Cardbus PCMCIA is also examined showing the compatibility with the TPS2205.

Power Supply Design for Power-over-Ethernet Applications

This application report illustrates two examples to monitor an incoming PWM signal using the versatile programmable high-end timer (N2HET). Both examples can be run in either the Hercules™ HDK or the LaunchPad board. The application report shows the N2HET program examples the steps to setting up the N2HET registers as well as basic system settings utilizing the HalCoGen.

This application report describes the features of the on-chip ROM for the TMS320C5517 device. Included is a description of the bootloader and how to interface with it for each of the possible boot dev

The TPS2400 has fixed turnon and turnoff thresholds of 3 V and 6.9 V respectively making it an ideal overvoltage protector for 3.3-V and 5-V loads that are 6.9-V tolerant. However many loads have an operating voltage that is greater than 6.9 V. To be compatible with these loads the overvoltage threshold of the protector circuit can be raised above 6.9 V using the scheme presented in this appli

Embedded applications commonly run in an environment where power consumption by the DSP and its peripherals needs to be minimized. However since DSP programs also need to meet time deadlines DSP power management can be a challenge.

The example provided with this application note showcases several power management techniques you can leverage in a DSP/BIOS-enabled application. As with most softw

This document describes the change made from bq27500-V100 to bq27500-V120. The latest ordering information and data sheet is on the TI Web site. Note that bq27500-V100 uses FW version 1.08 and the bq27500-V120 uses FW version 1.20.

This document describes the TLS223x servo-combine predriver its state machine phase comparator and voltage-controlled oscillator (VCO).
The TLS223x uses a phase-locked loop (PLL) to commutate a spindle motor. The selection of compensation values ensures the proper operation of the PLL. An example of the selection process for the TLS223x is provided.

For reasons of continuity in some systems independent power sources must operate in parallel. The traditional way to connect two ore more power sources in parallel uses isolation diodes. However in situations where the associated voltage drop or the presence of voltage-feedback sensing wires makes using isolation diodes undesirable special types of low dropout voltage regulators (LDOs) and hot-

Many servo applications require absolute position information as feedback. This document describes how the encoder count can be processed to obtain absolute position on the TMS320C240. The document in

Ultrasonic flow meters are gaining wide usage in commercial industrial and medical applications. Major benefits of utilizing this type of flowmeter are higher accuracy low maintenance (no moving parts) non-invasive flow measurement and the ability to regularly diagnose health of the meter. This application note is intended as an introduction to ultrasonic time-of-flight (TO

The optocoupler is often used in pulse-width-modulated power converters to transmit an error signal across an isolation boundary. This error signal is used on the primary side to close the control loop. This application note describes a typical optocoupler feedback scheme using the UC3965 Precision Reference with Low-Offset Error Amplifier and a Siemens Optoelectronics IL207 optocoupler. The discu
