The device features a typical on-resistance (Rds On) of 70mOhm, minimizing power loss in power management circuits. It utilizes an 8-SOIC surface-mount package.
Feature Summary
- Current-limited switching capability for dual USB port applications
- Minimizes power loss and improves efficiency in power management circuits
Applications
- USB port protection and power distribution
- Handheld medical devices requiring stable power supply
- General power management circuitry
Procurement Notes
Verify the specific suffix against official Analog Devices documentation to confirm exact packaging and temperature grade. Ensure the component matches the required 8-SOIC footprint and electrical specifications for your design. Cross-reference with Maxim Integrated datasheets for accurate pinout and thermal characteristics before integration.
Selection Notes
Select this component when designing circuits requiring independent current limiting for two USB interfaces. Consider the 70mOhm on-resistance for thermal performance and the 2.3A current limit for load handling. Verify compatibility with the 2.7V to 5.5V operating voltage range and ensure the 8-SOIC package fits the PCB layout constraints.
Part Context
The MAX1930ESA belongs to the Maxim Integrated power distribution switch family. It is engineered specifically for managing power delivery to multiple downstream loads, such as USB peripherals. The device integrates protection features to safeguard both the source and the connected loads from overcurrent conditions.
Replacement Considerations
Consult official Analog Devices substitution guides for verified alternatives. Ensure any replacement maintains the 8-SOIC package, 2.3A current limit, and compatible voltage range.
