VLA542-01R

DESCRIPTION VLA542 is a hybrid integrated circuit designed for driving n-channel IGBT modules in any gate-amplifier application. 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. Recommended IGBT modules: VCES = 600V series up to 600A class VCES = 1200V series up to 400A class FEATURES Electrical isolation between input and output with opto-coupler (Viso = 2500Vrms for 1minute) Two supply driver topology Built-in short circuit protection circuit(With a pin for fault out) CMOS compatible input interface HYBRID IC VLA542-01R Hybrid IC for driving IGBT modules OUTLINE DRAWING Dimensions : mm 44 MAX 26MAX 5.5MAX 2.54 1 0.5 +0.15 -0.1 14 5.5 MAX 5.5 MAX 4.5+/-1.5 0.25 0.2 0.1 3.0 MAX 8 MAX APPLICATIONS To drive IGBT modules for inverter or AC servo systems application BLOCK DIAGRAM VI + 14 VI - 13 LATCH DETECT CIRCUIT TIMER & RESET CIRCUIT INTERFACE OPTO-COUPLER 240 ohm GATE SHUTDOWN CIRCUIT 4 VCC 2 CONTROL PIN FOR ttrip 1 DETECT 5 VO 8 FAULT OUTPUT 6 VEE 3,7,9,10 pin : Non connection HYBRID IC VLA542-01R Hybrid IC for driving IGBT modules MAXIMUM RATINGS (unless otherwise noted, Ta=25°C) Symbol Parameter Conditions VCC Supply voltage VEE VI Input signal voltage DC Applied between; 13pin and 14pin 50% duty cycle, pulse width 1ms VO IOHP IOLP Viso Output voltage Output peak current Isolation voltage When the output voltage is “H” P...
