ISL6341CRZ-T

By integrating control, gate drivers, output adjustment, monitoring, and protection functions into a single 10 Ld Thin DFN package, the ISL6341CRZ-T streamlines the implementation of complex power management systems. This level of integration not only saves valuable board space but also reduces component count and overall system cost
