  • Figure:1 Timer Alarm Circuit 1

    Timer Alarm Circuit

    Posted Dec 20, 2014 By Credible Sport
    This circuit is a type of alarm system in which different values of resistors are used to adjust the triggering time of its buzzer. The design has fewer components than a conventional timing circuit. The circuit is supplied by a 9V DC source. The S1 is a switch that controls the supply. The S2 serves as a triggering switch in order to start the timer. The 500kΩ, 1MΩ, 1.5MΩ and 2.2MΩ…

    Solar Battery Charger

    Posted Dec 14, 2014 By Sudheer Gupta
    Here is the simple circuit to charge 6 V, 4.5 Ah rechargeable Lead-acid battery from the solar panel. This circuit may also be used to charge any battery at constant voltage because output voltage is adjustable.
  • Figure:4 Analog Interfacing Networks for DAC348x and Modulators

    Analog Interfacing Networks for DAC348x and Modulators

    Posted Dec 08, 2014 By Design Library
    The analog interface circuits in this reference design are often used between current-source based digital-to analog converters (DAC) and quadrature modulators. While the DAC348x is used as an example of a TI high-speed DAC, the circuits can be applied to other current-source based converters with slight modifications. The DAC348x and TRF3705 analog interface are populated by default on the…

    Automatic Safety Flasher

    Posted Dec 06, 2014 By Credible Sport
    This flasher is appropriate for use during the night. It furnishes a bright nighttime illumination, and shuts itself OFF automatically as soon as the sun comes up. The photocell must be mounted on top of the unit in such a way as to detect the greatest amount of available light.
  • Figure:6 High Performance Buck Converter with VID Interface to Supply TI TMS320 TCI6634

    High Performance Buck Converter with VID Interface to Supply

    Posted Dec 01, 2014 By Design Library
    The PMP7047 reference design uses the TPS56221 25A buck converter with the LM10010 6-bit VID interface chip to enable Adaptive Voltage Scaling (AVS) and tight voltage regulation of the TMS320 TCI6634 DSP core rail. At 300KHz switching frequency it  is optimized for high efficiency and low power loss, while keeping component count and PCB area small.
  • Figure:7 Circuit Diagram of Light Activated Switch

    Light Activated Switch Using LDR

    Posted Nov 30, 2014 By Sudheer Gupta
    Here, we are designing a simple light activated switch circuit using LDR. It can be used in security applications like when there is darkness on the LDR, it stops lighting.
  • Figure:8 Three-Phase Brushless DC Motor Driver

    Three-Phase Brushless DC Motor Driver

    Posted Nov 24, 2014 By Design Library
    The Thee-Phase Brushless DC Motor Driver reference design is a 10A, 3-phase brushless DC drive stage based on the DRV8301 pre-driver and CSD18533Q5A NextFET™ power MOSFET. It has three low side current sense amps (two internal to DRV8301, one external). The design also leverages a 1.5A step down buck converter, is fully protected with short circuit, thermal, and shoot-through protection, and is…
