This application report presents the steps necessary to update the bq20z80 firmware and the EVM.

TI's DRV91680 and DRV91690 are three-phase brushless DC (BLDC) motor controllers and predrivers. Only requiring external FETs, they are integrated solutions providing necessary analog and digital peripherals to create a robust motor solution. Having a programmable MSP430 core, the DRV91680 and DRV91690 are capable of controlling both sensored and sensorless motors by simply downloading the respective application code. This guide describes the application code for sensored motor control using Hall-effect sensors.

70Amps/100Amax high current ASIC core supply: four phases w/ 2x TPS40140: for use with 12V bus system

This reference design implements a video over LVDS solution for automotive infotainment applications.It highlights the support of multi-touch with haptic feedback: LCD backlight control: and ambient light sensing: without the introduction of dedicated support lines back to the host processor. This design is implemented using two boards. The main electronics board: SAT0059 is where the deserializer: microProcessor: backlight controller: haptics drivers and power supply are located. The LCD interface board: SAT0096: is a physical and electrical interface to a specific LCD panel. It connects to the SAT0059 through a Samtec board to board connector and provides connection points for the LCD panel: touchscreen: backlight connections and haptic drivers. The SAT0096 is designed for a Microtips UMSH-8596MD-20T display. If a different display is to be used: a new LCD Interface board would likely need to be designed.

Demonstration circuit 2071A features the LTC2373 family. The LTC2374/LTC2373/LTC2372 are low noise, high speed, 8-channel, 16/18-bit successive approximation register (SAR) ADCs. The demo manual refers to the LTC2373-18 but applies to all parts in the family, the only differences being the number of bits and the maximum sample rate. Operating from a single 5V supply, the LTC2373-18 has a highly configurable, low crosstalk, 8-channel input multiplexer, supporting fully differential, pseudo-differential unipolar and pseudo-differential bipolar analog input ranges.

This Verified Design provides the theory: component selection: simulation: PCB design: and measurement details for a low-side voltage-to-current (V-I) converter. The circuit delivers a well-regulated current to a floating load which could include actuators: sensors: motors: LEDs: and many other applications. The design uses the OPA735 small-signal op amp to control an NPN emitter-follower that sources current to the load. The current is accurately regulated by feeding back the voltage drop across a low-side current-sense resistor to the op amp. The rail-to-rail input/output topology of the OPA735 allows for good accuracy even at low currents because there is very little dead-zone" in either the input or output stage. The auto-zero zero-drift technology in the OPA735 allows for great DC performance over temperature.See more TI Precision Designs"

This application report provides a system-level functional description of the bq78PL114 circuitry and describes recommended system design and printed-circuit board layout techniques to ensure best performance.

The AD7980 is a 16-bit, successive approximation, analog-to-digital converter (ADC) that operates from a single power supply, VDD. It contains a low power, high speed, 16-bit sampling ADC and a versatile serial interface port. On the CNV rising edge, it samples an analog input IN+ between 0 V to REF with respect to a ground sense IN?. The reference voltage, REF, is applied externally and can be set independent of the supply voltage, VDD. Its power scales linearly with throughput.The SPI-compatible serial interface also features the ability, using the SDI input, to daisy-chain several ADCs on a single, 3-wire bus and provides an optional busy indicator. It is compatible with 1.8 V, 2.5 V, 3 V, or 5 V logic, using the separate supply VIO.The AD7980 is housed in a 10-lead MSOP or a 10-lead QFN (LFCSP) with operation specified from ?40?C to +125?C.APPLICATIONSAutomated test equipmentData acquisition systemsMedical instrumentsMachine automation

This active power factor correction: transition mode: isolated flyback generates a constant current of 350mA on an LED string from high line (180 to 264Vac). The output accepts a voltage range of 40 to 120V. Open LED protection (overvoltage) and safety discharge of output capacitors are implemented as well.

The CC2541EM (evaluation module) reference design contains schematics and layout files for the CC2541EM module. The reference design demonstrates good techniques for CC2541 decoupling and RF layout. For optimum RF performance: the reference design should be copied accurately.There are several reference designs to choose from; a 4-layer PCB reference design with an SMA antenna connector for RF output matched to 50 ohm or a 2-layer PCB reference design with the option of using an SMA antenna connector for RF output matched to 50 ohm or an on board inverted F antenna.
