ACFJ-332BT-000E

Overview

The ACFJ-332BT-000E is a dual-channel automotive-grade optocoupler featuring high-speed rail-to-rail gate drive outputs. It provides 5kV RMS isolation between inputs and two output channels with a minimum common-mode transient immunity of 150kV/μs. The device operates within a wide supply voltage range, supporting VDD1 from 3.0V to 5.5V and VDDA/VDDB from 10V to 25V. Key electrical characteristics include a maximum propagation delay of 70ns, channel skew of 15ns, peak output current of ±2.4A, and Miller clamp sink current of 1A. It includes programmable dead time, enable pins for functional safety, and under-voltage lockout protection.

Procurement Notes

Verify the specific suffix '000E' against official Broadcom documentation to confirm RoHS compliance and lead-free status. Ensure the package type matches the required SO-24 footprint. Confirm that the component meets AEC-Q100 Grade 1 requirements for your specific automotive application environment before finalizing procurement.

Selection Notes

Select this component when high-speed isolation with integrated gate drive capabilities is required in automotive environments. It is suitable for applications demanding strict functional safety standards due to its EN pin support. Consider the wide operating temperature range and high CMTI for noisy power electronics. Verify that the supply voltage ranges align with the system's logic and driver power rails.

Part Context

This part belongs to Broadcom's R2Coupler family, designed for enhanced insulation and reliability in harsh environments. It is specifically engineered for automotive and high-temperature industrial applications where signal integrity and safety are critical. The device integrates advanced protection features to simplify design-in processes for complex power conversion topologies.

Replacement Considerations

Check for direct substitutes within the ACPL-332 or ACFJ-3262 series if pin compatibility and electrical specifications match. Verify that any replacement maintains the same isolation voltage, CMTI rating, and automotive qualification status. Ensure the alternative supports the required gate drive current and propagation delay for the target application.
