The ACPL-31JT-000E from Broadcom is an Automotive Qualified Gate Drive Optocoupler that has been designed to offer fast propagation delay along with excellent timing skew performance. It requires an input voltage of 8 - 18 V and provides an output voltage of 12 - 20 V. This gate driver integrates MOSFETs, input and output drivers with active Miller control circuit, and protection circuits with a feedback loop. It is a fully-featured and easy-to-implement solution that includes smart features to protect the MOSFET during switching operations. This AEC-Q100 Grade 1 qualified gate driver consists of a direct LED input interface that allows for flexible logic configuration, and differential current mode drive having low impedance and negative gate bias, thereby improving noise immunity.

The ACPL-31JT-000E is equipped with desaturation sensing with shutdown protection and fault feedback, UVLO protection, and active miller current clamper circuits to detect and prevent false trigger or short-circuit-related damages. This RoHS 6-compliant driver IC is available in a surface-mount package that measures 10.363 x 7.493 mm and is ideal for automotive-isolated MOSFET gate drives, automotive DC-DC/AC-DC converters, and switching power supply applications.
