MAX4915AEUK+T

Current Regulation/Management Overview

The MAX4915AEUK+T is a single-channel current-limit switch from the MAX4915 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 200mA. The device provides low on-resistance and includes a guaranteed blanking time to prevent false triggering 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

• Internal current limiting protects host devices from damage caused by faulty load conditions or short circuits.
• Low on-resistance minimizes power loss and voltage drop during normal operation.
• Guaranteed blanking time prevents false current-limit activation when connecting capacitive loads.

Current Regulation/Management Applications

• SDIO card slot protection
• General-purpose load switching
• Portable electronic device power distribution

Current Regulation/Management Procurement Notes

Verify the specific suffix 'EUK' corresponds to the SOT-23-5 package and industrial temperature grade (-40°C to +85°C) as defined in the official datasheet. Confirm RoHS compliance status through the manufacturer's documentation. Ensure the selected variant matches the required 200mA current limit specification for the target application design.

Current Regulation/Management Selection Notes

Select this component when a single-channel solution with a fixed 200mA limit is required for low-voltage systems. Compare against the MAX4914B (100mA) and MAX4917A/B (300mA) variants if different current thresholds are needed. Consider the SOT-23-5 footprint constraints and thermal dissipation capabilities relative to the expected load profile.

Current Regulation/Management Part Context

This part belongs to the MAX491x family of current-limit switches designed for portable applications. The family offers various current limits (100mA, 200mA, 300mA) to suit different load requirements while maintaining a consistent interface and low-profile packaging for space-constrained designs.

Current Regulation/Management Replacement Considerations

Direct substitutes within the same family include MAX4914BEUK+T (100mA limit) and MAX4917BEUK+T (300mA limit), provided the current threshold adjustment is acceptable for the circuit design.
