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

Converter for Gate Drive

£ SIP Outline Allows More Space

on Mounting Area

£ Built-in Short-Circuit Protection

(With Fault Output)

£ Variable Fall Time on Short-

Circuit Protection

£ Electrical Isolation Voltage

Between Input and Output

(4000 Vrms for 1 Minute)

£ 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
