Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'GBG' against official Richtek documentation to confirm the exact package type and tape-and-reel specifications. Ensure the selected variant matches the required pinout and thermal characteristics for the target PCB layout. Cross-reference the full part number with manufacturer databases to confirm current production status and availability constraints.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a cost-effective, low-voltage high-side switch is required for USB interfaces. The 80mΩ on-resistance minimizes voltage drop, meeting strict USB compliance requirements. Choose this model over variants with lower current ratings if a 1.5A continuous load capacity is necessary for the application design.
