Avago/Broadcom: New smart gate drive optocoupler – ACPL-335J

The Broadcom ACPL-335J is a 2.5 A smart gate drive optocoupler device featuring fast propagation delay with excellent timing skew performance. The device supports a full set of fail-safe MOSFET diagnostics, protection and fault reporting. This full-featured and easy-to-implement gate drive optocoupler comes in a compact, surface-mountable SO-16 package.

The ACPL-335J is designed for driving power MOSFETs used in DC-DC converter, switching power supplies and battery chargers, and provides the reinforced insulation and reliability needed for critical high voltage industrial applications.

Avago is now Broadcom.
