Jul 11 2016 RECOM expands its low cost highly efficient R 78E switching regulator series with modules featuring 9V 12V and 15V output voltages. This series is designed to offer all of the advantages of a standard switching regulator high efficiency wide input range accurate output voltage regulation but at a lower cost. Like the existing 3.3V and 5V versions the
Making the Reset input high and the Set input low reverses the latch circuit s output state Q low and Q not high. This is known as the reset state of the circuit. If both inputs are placed into the low state the circuit s Q and Q not outputs will remain in their last states remembering their prior settings.
Feb 18 2014 Creating a composite op amp comes with its own set of design challenges. Delivering more than 200mA of output current can be a serious challenge for many high voltage operational amplifiers. But for high voltage applications requiring as much as 1A of current it is possible to meet this spec by pairing a current buffer with the op amp.
Dec 01 2019 After 24 h of self discharge the device can retain a relatively high voltage of 1.4 V initial voltage 1.8 V and drive a smart timer well for ca. 4 h revealing a low self discharge rate. This device also displays an almost equal capacity 97 mAh g −1 at 1 A g −1 under different bending states Fig. 5 e confirming its good
Jan 01 2016 The high output current density of the triboelectric nanogenerator is the first demonstration using rice husks as a source material. The area power density of the RH SiO2 triboelectric nanogenerator reaches 0.84 W m −2 with a peak short circuit current density of 5.7 mA m −2.Such a short circuit current density is almost among the highest reported value
Since the Arduino board or any microcontroller takes few seconds to boot in the meantime the Arduino pins fluctuate high and low several times including the pin where the MOSFETs are also connected. There could be a situation where both the output pins get high at the same time which could cause a short circuit via MOSFETs.

The S and R inputs won’t affect the output if you don’t have a trailing advantage on the clock pulse. But at the clock’s positive/leading edge the flip flop circuit is active and follows R and S input changes. Changes in one clock cycle include High S and low R = high output at the leading edge/ SET flip flop.

The centre pin is the output pin which provides an active high pulse whenever motion is detected. Otherwise this pin remains active low. That means a rising edge occurs when a PIR sensor detects motion. We can detect this rising edge with the help of interrupt pins of ESP8266. Here we have connected the output pin of the sensor with GPIO13.
In the first circuitthe NPN transistor switches the negative side of the coil. In the second circuitthe PNP transistor switches the positive side of the coil. The two circuits are otherwise identical. In what followsI ve concentrated on describing Timer . Howeverwhere appropriateI ve included an account of how Timer No.2 differs.

This 555 timer circuit will remain in either state indefinitely and is therefore bistable. Then the Bistable 555 timer is stable in both states HIGH and LOW . The threshold input pin 6 is connected to ground to ensure that it cannot reset the bistable circuit as it would in a normal timing application. 555 Timer Output
Stm32f103 has an internal PLL circuit from which we can generate clock signal of 72Mhz. We can go above 72Mhz but since stm32 works at max clock of 72Mhz so we did go above 72Mhz.
