EG3023

EG3023 is a cost-effective gate driver IC dedicated to high-power MOSFETs and IGBTs. It integrates a logic signal input processing circuit, dead-time control circuit, undervoltage lockout circuit, lockout circuit, level shift circuit, pulse filter circuit, and output driver circuit, designed specifically for drive circuits in brushless motor controllers. The EG3023 supports a high-side operating voltage up to 200V, a wide low-side Vcc supply voltage range of 7V~20V, and quiescent current consumption of less than 100uA. The IC features a lockout function to prevent simultaneous conduction of the output power transistors. The input channel HIN has a built-in 200K pull-down resistor, and LIN has a built-in pull-up to a high potential, ensuring both the high-side and low-side power MOSFETs remain off when the inputs are floating. Output current capability is I0+/-Δ 0.6/1A, housed in an SOP8 package.
