EG2185

EG2185 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, lockout circuit, level-shift circuit, pulse filter circuit, and output driver circuit, designed specifically for drive circuits in brushless motor controllers. The EG2185 supports a high-side operating voltage up to 600V, a wide low-side VCC supply voltage range of 10V~20V, and quiescent current consumption below 200μA. The IC features a lockout function to prevent simultaneous conduction of output power transistors. The HIN input channel has a built-in 250K pull-down resistor, and LIN has a built-in 5V pull-up, ensuring both high-side and low-side power MOSFETs remain off when inputs are floating. Output current capability is IO+/- 4/4A. Available in SOP8 package.
