Power MOSFET Gate Drive Optocoupler Broadcom ACPL-P346-060E with Compact Stretched SO6 Package
Broadcom ACPL-P346/W346 Optocoupler: High-Performance Gate Drive for Power MOSFETs
The Broadcom ACPL-P346/W346 is an optically isolated power output stage designed for driving power, GaN (Gallium Nitride), and SiC (Silicon Carbide) MOSFETs. Leveraging BCDMOS technology, this gate drive optocoupler offers enhanced peak output current, superior rail-to-rail output voltage, and double the speed of previous generations. Its high peak output current and short propagation delay are crucial for rapid MOSFET switching, enabling reduced dead time and improved system efficiency. The rail-to-rail output voltage ensures optimal MOSFET gate drive, minimizing power loss and facilitating lower system power consumption, making it suitable for bootstrap power supply operation. With a very high Common Mode Rejection (CMR) rating, it effectively handles significant common-mode noise in industrial motor drives and other power switching applications. The input features direct LED current drive with built-in hysteresis, preventing output oscillation and eliminating the need for external Schmitt trigger circuits. The compact Stretched SO6 package offers space savings and complies with industrial safety standards like IEC/EN/DIN EN 60747-5-5, UL 1577, and CSA.
