Under Voltage Lockout Feature. (Discussion applies to
ACPL-3130, ACPL-J313, and ACNW3130)
TheACPL-3130containsanundervoltagelockout(UVLO)
feature that is designed to protect the IGBT under fault
conditions which cause the ACPL-3130 supply voltage
(equivalent to the fully-charged IGBT gate voltage) to
drop below a level necessary to keep the IGBT in a low
resistancestate.WhentheACPL-3130outputisinthehigh

Dead Time and Propagation Delay Specifications. (Discus-
sion applies to ACPL-3130, ACPL-J313, and ACNW3130)
The ACPL-3130 includes a Propagation Delay Difference
(PDD)specificationintendedtohelpdesignersminimize
“dead time” in their power inverter designs. Dead time
is the time period during which both the high and low
side power transistors (Q1 and Q2 in Figure 29) are off.

Delaying the LED signal by the maximum propagation
delaydifferenceensuresthattheminimumdeadtimeis
zero, but it does not tell a designer what the maximum
deadtimewillbe.Themaximumdeadtimeisequivalent
to the difference between the maximum and minimum
propagation delay difference specifications as shown in
Figure40.ThemaximumdeadtimefortheACPL-3130is
700ns(=350ns-(-350ns))overanoperatingtemperature
rangeof-40°Cto100°C.
