ACPL-38JT-000E

Automotive Gate Drive Optocoupler with R²Coupler™ Isolation

Currently Viewing:

Broadcom's 2.5 Amp R2Coupler, Automotive Gate Drive Optocoupler, with Integrated Desaturation (VCE) Detection and Fault Status Feedback makes automotive IGBT VCE fault protection compact, affordable, and easy-to-implement while satisfying automotive AEC-Q100 Grade 1 semiconductor requirement.

Broadcom R2Coupler, Automotive Gate Drive Optocoupler, isolation products provide the reinforced insulation and reliability needed for critical automotive and high temperature industrial applications.

The ACPL-38JT is a highly integrated power control device that incorporates all the necessary components for a complete, isolated IGBT gate drive circuit with fault protection and feedback into one SO-16 package. TTL input logic levels allow direct interface with a microcontroller, and an optically isolated power output stage drives IGBTs with power ratings of up to 150 A and 1200 V. A high speed internal optical link minimizes the propagation delays between the microcontroller and the IGBT while allowing the two systems to operate at very large common mode voltage differences that are common in industrial motor drives and other power switching applications.
