Data Sheet
Description
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.
