Full Wave Rectifier Using Single Supply OPAMP

This is a Full wave rectifier project built using MAX44267 dual OPAMP which provides true zero output with a single supply. The circuit converts Bipolar/AC input into full-wave output. CN1 is provided for sinewave input, CN2 helps to connect the power and output. Operating supply 15V DC, D1 power LED.

The MAX44267 precision, low-noise, low-drift dual operational amplifier offers true-zero output that allows the output to cross zero maximizing the dynamic range of an ADC and increasing resolution. In addition, the input common-mode range extends from +13.5V down to -12V. The MAX44267 integrates charge-pump circuitry that generates the negative voltage rail in conjunction with external capacitors. This allows the amplifier to operate from a single +4.5V to +15V power supply, but it is as effective as a normal dual-rail ±4.5V to ±15V amplifier. The architecture eliminates the need for a negative power-supply rail, saving system cost and size. The MAX44267 is unity-gain stable with a gain-bandwidth product of 5MHz. The device features low offset voltage of 50μV (max), drift of 0.4µV/°C (max), and 200nVP-P noise from 0.1Hz to 10Hz. The low offset and noise specifications and wide input common-mode range make the device ideal for sensor transmitters and interfaces.  Varying the external charge pump capacitors enables the charge-pump noise to be minimized.

6V – 2.5Ah Sealed Lead-Acid Battery Charger

This dual-level float charger was designed for a 6V (three 2V cells) 2.5Ah battery. D2 LED was added for visual indication of charge completion, D3 indicates power, D4 LED presents overcharge condition, etc. 6V lead-acid battery charger is built using the UC3906 chip. UC3906 contains all of the necessary circuitry to optimally control the charge and hold cycle for sealed lead-acid batteries. UC3906 IC monitors and controls both the output voltage and current of the charger through three separate charge states; a high current bulk-charge state, a controlled over-charge, and a precision float-charge, or standby state. Optimum charging conditions are maintained over an extended temperature range with an internal reference that tracks the nominal temperature characteristics of the lead-acid cell. A typical standby supply current requirement of only 1.6mA allows these ICs to predictably monitor ambient temperatures. Separate voltage loop and current limit amplifiers regulate the output voltage and current levels in the charger by controlling the onboard driver. Voltage and current sense comparators are used to sense the battery condition and respond with logic inputs to the charge state logic.

A charge enable comparator with a trickle bias output can be used to implement a low current turn-on mode of the charger, preventing high current charging during abnormal conditions such as a shorted battery cell. Other features include a supply under-voltage sense circuit with a logic output to indicate when input power is present. In addition, the over-charge state of the charger can be externally monitored and terminated using the over-charge indicate output and over-charge terminate input.

Note: The circuit is configured to charge 6V – 2.5 to 4.5Ah Battery. Higher current and voltage batteries can be charged by changing resistors values, refer to the datasheet of UC3906 for the same.

Do not populate the following components: CN3, R14, R16, R17, R18 they are optional for microcontroller interface/control.

Features

  • Input Supply Voltage  0V to 13V DC, 1Amp – 2Amp
  • Bulk Charge Rate 500mA
  • 5AH To 4.5AH Battery Can be Charged
  • Start-up Trickle Current 10mA
