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
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
(2500 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

Description
VCE detection diode – fast recovery, Vrrm > VCES of IGBT being used (Note 1)
Detect input pin surge voltage protection (Note 2)
Gate surge voltage protection
VD supply decoupling – Electrolytic, long life, low Impedance, 105°C (Note 3)
DC/DC output filter – Electrolytic, long life, low Impedance, 105°C (Note 3,4)
Fault feedback signal noise filter
Adjust soft shutdown – Multilayer ceramic or film (see application note)
Adjust trip time – Multilayer ceramic or film (see application note)
Fault sink current limiting resistor
Fault signal noise suppression resistor
Fault feedback signal noise filter
Fault feedback signal pull-up
Opto-coupler for fault feedback signal isolation
74HC04 or similar – Must actively pull high to maintain noise immunity
Notes:
(1) The VCE detection diode should have a blocking voltage rating equal to or greater than the VCES of the IGBT
being driven. Recovery time should be less than 200ns to prevent application of high voltage to Pin 30.
(2) 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.
