Uninterrupted Power Supply in an IC Project


The Uninterrupted Power Supply in an IC . Cymbet Corporation announced the availability of the EnerChip™ CC CBC3105 smart solid state battery. The CBC3105 combines the award winning EnerChip battery with integrated input power conversion, battery management and regulated output capabilities. The Cymbet EnerChip™ CC is a smart rechargeable solid state battery Uninterrupted Power Supply (UPS in a Chip™) that provides power backup to microelectronic devices when main power fails. The EnerChip CC provides power supply monitoring and switches over to the internal solid state backup battery when the supply drops below a set threshold. The EnerChip CC product family can provide anywhere from several hours to several weeks of backup time.

The CBC3105 is an ideal solution for design engineers who need a compact device to back-up a Real Time Clock or Microcontroller during power failure where coin cell batteries or super caps will not work due to size, reliability, no battery doors, no battery replacement, battery disposal issues, or need for life-of-product power. The CBC3105 uses surface mount/reflow solder assembly and is RoHS tested-compliant. 

The EnerChip CC device family can accomplish all this in a footprint as small as the CBC3105 4mm x 5mm x 0.9mm package that is priced as low as $0.50 in high volumes. The EnerChip CC CBC3112 and CBC3150 provide even more energy storage in similar small footprint packages. The CBC3105 can be purchased at Avnet, Avnet Abacus, Avnet Asia, Digi-Key, Mouser and Farnell.
Easy-to-Use Evaluation Kits for Power Backup Applications
Cymbet makes it easy to design EnerChips into new products by offering two EnerChip CC evaluation kits:
  • CBC-EVAL-05 EnerChip CC Evaluation Kit which contains everything needed to test EnerChip 12uAh and 50uAh thin film batteries, EnerChip CC CBC3112 and CBC3150 batteries with Integrated Battery Management, and to test multiple batteries in parallel. This kit will also include a CBC3105 evaluation board for experimenting with this device.
  • CBC-EVAL-06 Real-Time-Clock Evaluation Kit: includes a Microcrystal NV2123 Real-Time Clock device and a CBC3112 EnerChip CC for battery backup. This kit also includes a Windows based Graphical User Interface to set the clock & test operation in RTC back up and count-down modes.
Visit Cymbet at Design West/ESC Booth 2330 for UPS in a Chip Demos
At booth 2330 at Design West/ESC 2012 at the San Jose Convention Center March 27-29, 2012, Cymbet will demonstrate tiny footprint power backup solutions that give designers the ability to create optimized products. By providing all the functions of a UPS system in a single chip, the EnerChip CC batteries enable a new class of products that utilize life-of-product energy storage.

Electronic Extended Play Circuit Diagram

This is a Electronic Extended Play Circuit Diagram. A single op amp-one of four contained in the popular LM324-is operating in a variable pulse width, free-running square wave oscillator circuit, with its timed output driving two transistors that control the on/ off cycle of the tape-drive motor. The Oscillator` s positive feedback path holds the secret to the successful operation of the variable on/ off timing signal.   Electronic Extended Play Circuit Diagram The two diodes and pulse width potentiometer R8 allows the setting of the on and off time, without affecting the oscillator`s operating frequency. One diode allows only the discharge current to flow through it and the section of R8 that it`s connected to. The other diode, and its portion of R8, sets the charge time for the timing capacitor, C3. Since the recorder`s speed is controlled by the precise off/on timing of the oscillator, a simple voltage-regulator circuit (Ql, R3, and D4) is included.  Connecting the spe...

Power Amplifier with voltage regulator 4 × 50 Watt TDA8588

Power Amplifier with voltage regulator 4 × 50 Watt TDA8588    The TDA8588 is a multiple voltage regulator combined with four independent audio power amplifiers configured in bridge tied load with diagnostic capability. The output voltages of all regulators except regulators 2 and 3 can be controlled via the I2C-bus. However, regulator 3 can be set to 0 V via the I2C-bus. The output voltage of regulator 2 (microcontroller supply) and the maximum output voltage of regulator 3 (mechanical digital and microcontroller supplies) can both be either 5 V or 3.3 V depending on the type number. The maximum output voltages of both regulators are fixed to avoid any risk of damaging the microcontroller that may occur during a disturbance of the I 2C-bus. The amplifier diagnostic functions give information about output offset, load, or short-circuit. Diagnostic functions are controlled via the I2C-bus. The TDA8588 is protected against short-circuit, over-temperature, open ground and open VP ...

Digital Voltmeter Circuit with ICL7107

Description. The circuit given here is of a very useful and accurate digital voltmeter with LED display using the ICL7107 from Intersil. The ICL7107 is a high performance, low power, 3.5 digit analog to digital converter. The IC includes internal circuitry for seven segment decoders, display drivers, reference voltage source and a clock. The power dissipation is less than 10mW and the display stability is very high. The working of this electronic circuit is very simple. The voltage to be measured is converted into a digital equivalent by the ADC inside the IC and then this digital equivalent is decoded to the seven segment format and then displayed. The ADC used in ICL7107 is dual slope type ADC. The process taking place inside our ADC can be stated as follows. For a fixed period of time the voltage to be measured is integrated to obtain a ramp at the output of the integrator. Then a known reference voltage of opposite polarity is applied to the input of the integrator and allowed to r...
