MAX1823BEUB+

Overview

The MAX1823BEUB+ is a dual USB power distribution switch designed for portable and consumer electronics. It operates within a supply voltage range of 4V to 5.5V and features current limiting with auto-reset functionality. The device includes fault blanking to prevent false triggering during inrush events. It supports an operating temperature range from -40°C to +85°C and draws a typical supply current of 50µA. The component is housed in a 10-pin µMAX package, suitable for surface-mount applications requiring compact footprints.

Feature Summary

• Dual channel configuration for independent USB port control
• Integrated fault blanking mechanism to ignore transient inrush currents
• Auto-reset protection that automatically restores power after fault clearance
• Current-limited switching capability for overcurrent protection

Applications

• USB peripheral connectivity hubs
• Portable computing devices
• Consumer electronics power management

Procurement Notes

Verify the exact ordering suffix matches the required package variant. Confirm the manufacturer designation aligns with Analog Devices or Maxim Integrated specifications. Ensure the component status is active before procurement. Cross-reference the datasheet revision to guarantee compatibility with design requirements. Validate the pinout configuration against the specific application schematic.

Selection Notes

Select this component when dual-channel USB power distribution with automatic recovery is required. Consider the 10-pin µMAX package size for space-constrained designs. Evaluate the 50µA supply current for battery-operated applications. Verify that the 4V to 5.5V input range matches the system power rails. Assess the need for fault blanking to handle high-inrush loads safely.

Part Context

This part belongs to the MAX1823 family of USB switches. It shares functional similarities with other dual-switch variants but differs in package and specific electrical characteristics. The BEUB+ suffix indicates a specific commercial grade and tape-and-reel packaging option. It is distinct from single-channel or non-auto-reset counterparts in the same product line.

Replacement Considerations

Potential substitutes include MAX1823AEUB+ for alternative grading or MAX1823AEUB+T for different packaging formats. Verify pin compatibility and electrical parameters before substitution. Consult official cross-reference guides for validated alternatives.
