Procurement Notes

Verify the specific suffix 'CVB+' against the official Analog Devices or Maxim Integrated datasheet to confirm the commercial grade temperature rating and packaging variant. Ensure the ordering part number matches the required tape-and-reel or tray configuration as specified in the manufacturer's latest documentation before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring strict adherence to USB BC 1.2 detection protocols for peripheral devices. Consider the 10-UTQFN footprint constraints and the 0°C to 70°C operating temperature range during thermal and mechanical design phases. Verify compatibility with the host system's 3.5V to 5.5V supply rails.

Part Context

This part belongs to the Maxim Integrated portfolio, now part of Analog Devices Inc. It functions as a specialized power management integrated circuit (PMIC) focused on USB charging detection rather than general-purpose power regulation. It serves as a critical interface component for managing power negotiation between USB hosts and connected peripherals.

Replacement Considerations
