MAX4917AEUK+T

Current Regulation/Management Overview

The MAX4917AEUK+T is a single-channel current-limit power switch IC from the MAX4917 family, manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.3V to 5.5V and features an internal current limit of 100mA. The device provides low on-resistance of 0.2Ω maximum and includes a guaranteed blanking time of 14ms to handle transient voltages during load connection. It is housed in a compact SOT-23-5 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Current Regulation/Management Feature Summary

• Integrates internal current limiting to protect host devices from faulty load conditions
• Features low shutdown reverse current for efficient power management
• Includes a guaranteed blanking time to ensure transient voltage settling

Current Regulation/Management Applications

• SDIO port protection and load switching
• General-purpose load switching applications
• Power distribution circuits requiring overcurrent protection

Current Regulation/Management Procurement Notes

Verify the specific suffix 'EUK' against the manufacturer's official datasheet to confirm pinout and electrical specifications. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the part number with authorized distributors to confirm availability status, as supply constraints may apply to this specific variant.

Current Regulation/Management Selection Notes

Select this component when a single-channel solution with a fixed 100mA current limit is required. It is suitable for applications needing low on-resistance and fast response to overcurrent events. Consider the SOT-23-5 package size for space-constrained designs. Verify that the 2.3V to 5.5V input voltage range aligns with the system power rails.

Current Regulation/Management Part Context

This part belongs to the MAX4917A/B series of current-limit switches, which also includes variants with 200mA and 300mA limits such as the MAX4917B. These devices are designed for portable electronics and industrial systems where robust load protection is critical. The family shares similar architectural features but differs in current threshold settings and package options.

Current Regulation/Management Replacement Considerations

Direct substitutes include other members of the MAX4917 family, such as MAX4917BEUK+T for higher current capacity. Verify compatibility with existing PCB footprints and control logic levels before substitution.
