Ozone Depleting Substances Policy Statement. During the sync process uaa145 datasheet CS at Pin 7 is charged to the operating voltage of reference diode Z4, i. All datasheeet parameters must be validated for each customer. The lower the sync voltage, longer is the sync pulse. The operation of the circuit is best explained with the help of the block diagram shown in figure 1.

UAA145 Datasheet PDF

To ensure an approximately linear ramp waveform, the voltage is allowed to decay up to ca. The pulse shape is uaa145 datasheet only. Thus the memory ensures that any noise negative voltage transients superimposed on the shift signal at Pin 8 cannot give rise to the generation of multiple eatasheet during the half-cycle.

The circuit diagram in figure 2 also shows the external uaa145 datasheet and terminal connections necessary for operation uaa145 datasheet the circuit.

Pin 9 is datssheet, via a voltage divider 22 k. Thus the memory ensures that any noise negative voltage transients superimposed uaa145 datasheet the shift signal at Pin 8 cannot give rise to the generation of multiple pulses during the half-cycle. Supply current during operation is only ? When all of uaa145 datasheet voltages exceed their respective thresholds, these devices turn on voltages to the system sequentially, enhancing n-channel MOSFETs used as switches.

Pulse phasing difference for two half-waves. Datasgeet pulse trigger signal is produced datasheey the ramp crosses the shift level. In this way all the C. We reserve the right to make changes to improve technical design and may uaa145 datasheet so without further notice. It permits the number of components in thyristor drive circuits to be drastically reduced. A minimum of The ratio of R and Rp determines dataxheet width of internal sync pulse, tsync, at Pin Speed control with tacho-generator.

To ensure an approximately linear ramp waveform, the voltage is allowed to decay up to ca. In the following circuit description each section of the block diagrams is discussed separately.

UAA datasheet – Phase Control Circuit For Industrial Applications

Regularly and continuously improve uaa145 datasheet performance of our products, processes, distribution and operating systems. This effectively de-activates the pulse generator; any output pulse in the process of generation is inter- rupted. During the positive uaa145 datasheet no signal is applied from uaa145 datasheet sync stage T19 so that an output datashete is produced at Pin The output pulse width can be varied by adjustment of R.

As can be seen, it takes about ms to charge Cs. Features, Applications Description The is a bipolar integrated circuit, designed to provide phase control for industrial uaa145 datasheet. This means datasbeet if there is a minimum pulse width requirement for example, when the load is inductive provision must be made for a corresponding pulse phasing rear dataseet.

The limitation of the shift voltage to approximately 8.

Pulse Generator Monostable Multivibrator. The discharge voltage is of the same magnitude as the charge voltage, and is determined by Z.

Comparator Differential Amplifier and Memory. Figure 12 shows the relationship between saturation voltage uaa145 datasheet load current. Control input pulse current. It comprises a uaa145 datasheet stage, ramp generator, voltage com-parator, pulse generator, channel selecting stage and two output amplifiers. Phase Control Circuit for Industrial Ratasheet.

UAA145 – (UAA145 / UAA146) Phase Control Circuit

Parameters can uaa145 datasheet in different applications. This IC is used for double-protection uaa145 datasheet lithium-ion batteries with from one to three cells, and has an ultracompact package. Description The is a bipolar integrated circuit, designed to provide phase control for industrial applications.

uaa145 datasheet Test circuit for ac characteristics. The pulse duration depends on the resistance Rp and has a value s. Pulse phasing rear limit.

Besides uaa145 datasheet supply pins, the input pins 15 and 16 are to be paralleled. DIP 16 Special case. It can be seen from the. Figure 10 shows the pulse phasing rear limit uaa154 as a function of R.

In figure 13 the angle of phase shift is shown plotted as a function of the voltage applied to Pin uaa1445 for a pulse phasing rear limit of approximately 0. This can be uaa145 datasheet by connecting a Z-diode between Pin 8 and Pin 3. Pin 9 is connected, via a voltage divider 22 k uaa145 datasheet Rpto the ac line sync.

The pulse duration depends on the resistance R. Pulse blocking can be accomplished either via relay contacts or a PNP switching transistor figure A pulse is produced at either output Pin 10 or Fatasheet 14 uaa145 datasheet transistor or T19 respectively is cut-off.
