USB Type C Integrated Power Splitter designed for smartphones

The SLG59H1302C’s 130 V surge protection rating is 30% stronger than the competition and its 20-nanosecond reaction time to OVP events is at least seven times faster. It’s faster OVP response time protects sensitive downstream components from possible damage. Even though designed to operate with 5, 9, or 12V power adapters, the SLG59H1302C does not suffer damage even if 20V power adapters are mistakenly used.

In applying Silego’s proprietary MOSFET design IP, the Company’s design engineers deftly packaged two high-performance nFET transistors into a pcb-space-efficient 5mm2 WLCSP footprint no larger than the competition. In fact, the SLG59H1302C’s VBUS-to-VOUT RDSON is 47% smaller, and it’s VBUS-to-VSYS RDSON is 31% smaller than existing solutions. Because of these high-performance nFETs, the SLG59H1302C’s very low operating thermal gradients enable higher component packing density and ease system thermal design.
