Robust Gate Driver Photo Coupler MIRACLE POWER MP343W T3 G B for Industrial Inverter Applications
Product Overview
The MP343 Series is a high-performance Gate Driver Photo Coupler designed by Miracle Technology Co., Ltd. Featuring a 4.0A maximum peak output current and a wide operating temperature range of -40C to 110C, this device is engineered for demanding industrial applications. It utilizes an AlGaAs LED optically coupled to an integrated circuit with a power output stage, making it ideal for driving power IGBTs and MOSFETs in motor control inverters. The MP343 Series offers rail-to-rail output voltage, fast propagation delays, and robust Common Mode Rejection (CMR), ensuring reliable performance in switching power supplies, industrial inverters, and AC/DC motor drives. It also includes Under Voltage Lock-Out (UVLO) protection with hysteresis for enhanced operational safety.
