Overview
The MAX1940EEE+ is a triple USB power distribution switch manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 4V to 5.5V and supports an operating temperature range from -40°C to +85°C. The device features built-in current limiting with autoreset functionality and includes a 20ms fault blanking circuitry to prevent nuisance tripping during transient events.
Feature Summary
- Integrates three independent USB power switches for efficient power distribution management
- Provides automatic system recovery through integrated autoreset capability after fault clearance
- Includes dedicated fault blanking circuitry to ignore short-duration transients and avoid false triggering
Applications
- USB peripheral power management
- Portable computing devices
- Consumer electronics hubs
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required package and temperature grade. Request original datasheets and test reports to ensure compliance with electrical specifications before integration into design projects.
Selection Notes
Select this component when designing systems requiring isolated control of multiple USB ports with automatic protection recovery. Ensure the input voltage stays within the 4V to 5.5V range. Consider the thermal performance in enclosed designs due to power dissipation during active switching operations.
Part Context
This part belongs to the Maxim Integrated family of USB power switches designed for portable applications. It replaces older discrete protection schemes by integrating multiple channels into a single compact package, reducing board space and simplifying schematic design for multi-port USB interfaces.
Replacement Considerations
Consult official cross-reference lists for verified substitutes. Ensure replacement parts maintain identical pinout compatibility and electrical ratings to guarantee functional equivalence without redesign.
