Description:
VLA500K-01R is a hybrid
integrated circuit designed for
driving IGBT modules. This device
is a fully isolated gate drive circuit
consisting of an optimally isolated
gate drive amplifier and an isolated
DC-to-DC converter. The gate
driver provides an over-current
protection function based on
desaturation detection.
Features:
£ Built-in Isolated DC-to-DC
£ SIP Outline Allows More Space
£ Built-in Short-Circuit Protection
£ Variable Fall Time on Short-
£ Electrical Isolation Voltage
£ TTL Compatible Input
Application:
To drive IGBT modules for inverter
or AC servo systems applications
Recommended IGBT Modules:
600V module up to 600A
1200V module up to 1400A
1700V module up tp 1000A

... DZ1 is necessary to protect Pin 30 of the driver from voltage surges during the recovery of D1. (3) Power supply input and output decoupling capacitors should be connected as close as possible to the pins of the gate driver. (4) DC-to-DC converter output decoupling capacitors must be sized to have appropriate ESR and ripple current capability for the IGBT being driven.  VLA500K-01R ...

... Adjustment of Soft Shutdown Speed NO As noted above the VLA500K-01R provides a soft turn- off when a short circuit is detected in order to help limit the transient voltage surge that occurs when large short circuit currents are interrupted. The default shutdown speed will work for most applications so adjustment is usually not necessary ...
