Description:
VLA500-01 is a hybrid integrated
circuit designed for driving IGBT
modules. This device is a fully
isolated gate drive circuit consist-
ing 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
