High Current Gate Driver ISOMICRON ICPL-343W-500EAXW Photocoupler for Switching Power Supply Systems
Product Overview
The ICPL-343 series Photocoupler is a high-performance gate driver designed for driving power IGBTs and MOSFETs in motor control inverter applications and power supply systems. It features a 5.0A maximum peak output current, rail-to-rail output voltage, and a fast 110 ns maximum propagation delay. The device includes Under Voltage Lock-Out (UVLO) protection with hysteresis and operates over a wide supply voltage range of 15 to 30 Volts (VCC). Performance is guaranteed across an extended temperature range of -40C to +110C. The ICPL-343 is ideally suited for IGBT/MOSFET gate drive, uninterruptible power supplies (UPS), industrial inverters, AC/Brushless DC motor drives, and switching power supplies.
