The LED is optically coupled to an integrated circuit with a power output stage. The optocohpler operating voltage range of the output stage provides the drive voltages required by gate controlled devices. Contact Hewlett-Packard sales representative or authorized distributor. Option data sheets available. Measured from input terminals to output terminals, shortest distance path along body.
Insulation thickness between emitter and detector; also known as optocouplet through insulation. These dimensions are needed as a starting point for the equipment designer when determining the circuit insulation requirements. However, once mounted on a printed circuit board, minimum creepage and clearance requirements must be met as specified for individual equipment standards.
For creepage, the shortest distance path along the surface of a printed circuit board between the solder fillets of the input and output leads must be considered. There are recommended techniques such as grooves and ribs which may be used on a printed circuit board to achieve desired creepage and clearances.
Creepage and clearance distances will also optoocupler depending on factors such as pollution degree and insulation level. Maintenance of the safety data shall be ensured by means of protective circuits.

Device considered a two-terminal device: Pins 1 and 4 need to be connected to LED common. I OH Test Circuit. I OL Test Circuit. This results in lower peak currents more margin than predicted by this analysis. When negative gate drive is not used VEE in the previous equation is equal to zero volts. The value of 4. The thermal resistance values given in this optocoipler can be used to calculate the temperatures at each node for a given operating condition. However, this shield does not eliminate the capacitive coupling between the LED and optocoupler pins as shown in Figure Techniques to keep the LED in the proper state are discussed in the next two sections.
This is achieved by overdriving the LED current beyond the input threshold so that it is not pulled below the threshold during a transient. Figure 33 potocoupler an alternative drive circuit which, like the recommended application circuit Figure 25does achieve ultra high CMR performance by shunting the LED in the off state.
Under Voltage Lock Out. Dead time is the time period during which both the high and low side power transistors Q1 and Q2 in Figure 25 are off.
Any overlap in Q1 and Q2 o;tocoupler will result in large currents flowing through the power devices between the high and low voltage motor rails. Waveforms for Dead Time.
To minimize dead time in a given design, the turn on opticoupler LED2 should be delayed relative to the turn off of LED1 so that under worst-case conditions, transistor Q1 optodoupler just turned off when transistor Q2 turns on, as shown in Figure Delaying the LED signal by the maximum propagation delay difference ensures that the minimum dead time is zero, but it does not tell a designer what the maximum dead time will be.
The maximum dead time is equivalent to the difference between the maximum and minimum propagation delay difference specifications as shown in Figure Note that the propagation delays used to calculate PDD and dead time are taken at equal temperatures and test conditions since the optocouplers under consideration are typically mounted in close proximity to each other and are switching identical IGBTs.
