EG2121 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 shutdown circuit, lockout circuit, level shift circuit, pulse filtering circuit, and output drive circuit. It is specifically designed for the drive circuit in brushless motor controllers. Its high-end operating voltage can reach 250V, and the low-end VCC power supply voltage range is wide from 10V to 20V, with low static power consumption. This chip has a locking function to prevent the output power transistors from conducting simultaneously. The input channel HIN has a 200K pull-down resistor and LIN has an internal pull-up to 5V, which keeps the upper and lower power MOS transistors in a closed state when the input is suspended. The output current capability is 10+/-0.8/1.2A, and it is packaged in SOP8.
