EG Micro EG3112

EG3112 is a cost-effective gate driver IC dedicated to high-power MOSFETs and IGBTs. It integrates logic signal input processing, dead-time control, lockout, level shift, pulse filtering, and output driver circuits, designed specifically for drive circuits in brushless motor controllers.

The EG3112 supports a high-side operating voltage up to 600V, a wide low-side Vcc supply range of 2.8V~20V, and quiescent current consumption below 5uA. The IC features a lockout function to prevent simultaneous conduction of output power transistors. The HIN and LIN input channels incorporate built-in 200K pull-down resistors to keep both high-side and low-side power MOSFETs off when inputs are floating. Output current capability is I0+/-Ω2/2.5A, packaged in SOP8.
