Any overlap in Q1 and Q2 conduction will result in large currents flowing through the power devices between the high and low voltage motor rails. The Input-Output Momentary Withstand Voltage is a dielectric voltage rating that should not be interpreted as an input-output continuous voltage rating.

These dimensions are needed as a starting point for the equipment designer when determining the circuit insulation requirements. Temperature Figure 3 VOH vs. Device considered a two-terminal device: Minimum External Tracking L Creepage 7.

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. 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.

AVEN — March 21, To minimize dead time in a given design, the turn on of LED2 should be delayed relative to the turn off of Datzsheet so that under worst-case conditions, transistor Q1 has just turned off when transistor Q2 gcnw3120 on, as shown in Figure Lab 9 in this note. When negative gate drive is not datashheet VEE in the previous equation is equal to zero volts. Maintenance of the safety data shall be ensured by means of protective circuits.

Pins 1 and 4 need to be connected to LED common. Techniques to keep the LED in the proper state are discussed in the next two sections.

Dead time is datasgeet time period during which both the high and low side power transistors Q1 and Q2 in Figure 25 are off. Figure 33 is an alternative drive circuit which, like dataasheet recommended application circuit Figure 25does achieve ultra high CMR performance by shunting the LED in the off state.

For the continuous voltage rating refer to your equipment level safety specification or Broadcom Ltd. In this test, VOH is measured with a dc load current.

Documents Flashcards Grammar checker. There are recommended techniques such as grooves and ribs which may be used on a printed circuit board to achieve desired creepage and clearances. Data subject to change. 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.

Contact your Avago Technologies sales representative or authorized distributor for information. Creepage and clearance distances will also change depending on factors such as pollution degree and insulation level. The LED is optically coupled to an integrated circuit with a power output stage.

Option data sheets are available. To order, choose a part number from the part number column and catasheet with the desired option from the option column to form an order entry.

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

The high operating voltage range of the output stage provides the drive voltages required by gate controlled devices. 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 gcnw3120 in close proximity to each other and are switching identical IGBTs.

Contact an Avago Technologies sales representative or authorized distributor. See Applications section for additional details on limiting IOH peak.

This results in lower peak currents more margin than predicted by this analysis. However, this shield does not eliminate the capacitive coupling between the LED and optocoupler pins 5—8 as shown in Figure The thermal resistance values given in this model can be used to calculate the temperatures at each node for a given operating condition.

However, once mounted on a printed circuit board, minimum creepage and clearance requirements must be met as specified for individual equipment standards.
