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. Creepage and clearance distances will also change depending on factors such as pollution degree and insulation level. However, once mounted on a printed circuit board, minimum creepage and clearance requirements must be met as specified for individual equipment standards. To minimize dead time in a given design, the turn on of LED2 should be delayed relative chnw3120 the turn off of LED1 so that under worst-case conditions, transistor Q1 has just turned off when transistor Q2 turns on, as shown in Figure Delaying the LED datashee 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.

Minimum External Tracking L Creepage 7. 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.

Techniques to keep the LED in the proper state are discussed in the next two sections.

Temperature Figure 3 VOH vs. Maintenance of the safety data shall be ensured by means of protective circuits.

There are recommended techniques such as grooves and ribs which may be used on a printed circuit board to achieve desired creepage and clearances. The thermal resistance values given in this model can be used to calculate the temperatures at each node for a given operating condition. For the continuous voltage rating daatasheet to your equipment level safety specification or Broadcom Ltd.

AVEN — March 21, Lab 9 in this note. When negative gate drive is not used VEE in the previous equation is equal to zero volts.

Documents Flashcards Grammar checker. This capacitive coupling causes perturbations in the LED current during common mode transients and becomes the major source of CMR failures for a shielded optocoupler.

Any overlap in Q1 and Q2 conduction will result in datsaheet currents flowing through the power devices between the high and low voltage motor bcnw3120. Data subject to change. Option data datasheeet are available. The high operating voltage range of the output stage provides the drive voltages required by gate controlled devices. Device considered a two-terminal device: Contact an Avago Technologies sales representative or authorized distributor.

Contact your Avago Technologies sales representative or authorized distributor for information. Figure 33 is 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.


Dead time is the time period during which both the high and low side power transistors Q1 and Q2 in Figure 25 are off. See Applications section for additional ncnw3120 on limiting IOH peak.

The LED is optically coupled to an integrated circuit with a power output stage. To order, choose a part number from the part number column and combine with the desired option from the option column to form an order entry.

This is achieved by overdriving datashest LED current beyond the input threshold so that it is not pulled below the threshold during a transient.

However, this shield does not eliminate the capacitive coupling between the LED and optocoupler pins 5—8 as shown in Figure These dimensions are needed as a starting point for the equipment designer when determining the circuit insulation hcnw1320.

In this test, VOH is measured with a dc load current.

This results in lower peak currents more margin than predicted by this analysis. The Input-Output Momentary Withstand Voltage is a dielectric voltage rating that should not be interpreted as an input-output continuous voltage rating. Pins 1 and 4 need to be connected to LED common.
