EG2234 is a high cost-effective high-power MOS transistor and IGBT transistor gate drive dedicated chip, which integrates logic signal input processing circuit, dead zone control circuit, undervoltage protection circuit, lockout circuit, level shift circuit, pulse filtering circuit, and output drive circuit. The high-end operating voltage can reach 200V, while the low-end VCC power supply voltage range is wide from 5V to 20V. The chip has a locking function to prevent the output power transistors from conducting simultaneously. The input channels HIN and LIN have built-in pull-down resistors, which keep the upper and lower power MOS transistors in a closed state when the input is suspended. The output current capability is IO+1.5A/2.0A.
