ACFJ-332BT-500E

Overview

The ACFJ-332BT-500E is a dual-channel automotive-grade high-speed optocoupler featuring rail-to-rail output gate drivers. It provides 5kVRMS isolation between inputs and outputs with a minimum common-mode transient immunity of 150kV/μs. The device operates within an extended temperature range of -40°C to +125°C and utilizes a compact SO-24 surface-mount package. Key electrical specifications include a maximum propagation delay of 70ns, channel skew under 15ns, and peak output currents of ±2.4A.

Feature Summary

• Active Miller clamp functionality for robust switching performance
• Programmable dead-time generation compatible with TTL and CMOS logic
• Integrated enable pin supporting system functional safety requirements
• Under-voltage lockout protection with hysteresis for input and driver supplies

Applications

• Automotive powertrain DC-DC converters
