Optocoupler power output stage Broadcom ACPL-W343-000E for driving IGBTs and MOSFETs in motor control
Product Overview
The Broadcom ACPL-P343 and ACPL-W343 are optically isolated power output stages designed for driving power IGBTs and MOSFETs in motor control inverter applications. These optocouplers feature an integrated circuit with a power output stage, offering a high operating voltage range suitable for gate-controlled devices. They deliver high peak output current and rail-to-rail output voltage, enabling direct driving of IGBTs up to 1200V/200A or driving discrete power stages for higher-rated IGBTs. Key advantages include high common-mode rejection (CMR), under-voltage lockout (UVLO) protection, and a wide operating temperature range. The ACPL-P343 and ACPL-W343 are housed in a compact Stretched SO6 package, facilitating smaller and more efficient designs. They are ideal for applications such as AC and brushless DC motor drives, renewable energy inverters, industrial inverters, and switching power supplies.
