Description:
VLA507 is a hybrid integrated
circuit designed for driving IGBT
modules. This device operates
as an isolation amplifier for these
modules and provides the required
electrical isolation between the
input and output with an opto-
coupler.
Features:
£ Output is ±3 Amperes Maximum
£ Two Supply Drive
(VCC: 15 Volts, VEE: -10 Volts)
£ SIP Outline Allows More Space
on Mounting Area
£ Electrical Isolation Voltage
Between Input and Output
(2500 Vrms for 1 Minute)
£ TTL Compatible Input
Application:
To drive IGBT modules for welding,
induction heating, or inverters.
Recommended IGBT Modules:
NFH Series IGBTs –
VCES = 1200V up to
150A class (f: up to 30kHz)
NF Series IGBTs –
VCES = 600V up to
200A class (f: up to 20kHz)
VCES = 1200V up to
150A class (f: up to 20kHz)

Notes:
(1) Power supply decoupling capacitors should be connected as close as possible
to the pins of the gate driver.
(2) Power supply decoupling capacitors should be good quality, low ESR types.
(3) Printed circuit layout should minimize wiring lengths and utilize shielding layers
to suppress noise.
