Frequently Asked Questions

What types of loads can the L6376 device drive?

It is designed for driving inductive, capacitive, or resistive loads according to IEC 801-4 standards.

What protection features are built into this switch?

The device includes features such as internal current limitation, over-current protection, thermal shutdown, and undervoltage lockout.

How can I monitor the status of the L6376?

The DIAG pin is an open drain output that reports the IC's working condition, turning low when issues like undervoltage, overcurrent, or overtemperature occur.
