EG2181D

EG2181D is a cost-effective gate driver IC dedicated to high-power MOSFETs and IGBTs. It integrates a logic signal input processing circuit, level-shift circuit, pulse filter circuit, and output driver circuit, designed specifically for drive circuits in brushless motor controllers. The EG2181D supports a high-side operating voltage up to 600V, with a wide low-side Vcc supply voltage range of 10V~20V and a quiescent current of approximately 200μA. The HIN and LIN input channels feature a built-in 200K pull-down resistor, which keeps both the high-side and low-side power MOSFETs in the off state when the inputs are floating. Output current capability is 10±2A/2.5A, housed in a SOP8 package.
