MAX4915AEUK/V+T

Current Regulation/Management Overview

The MAX4915AEUK/V+T is a current-limit switch from the MAX4915A/B family, designed for power distribution and load switching applications. It features an internal current limit of 200mA to protect host devices from faulty load conditions. The device operates within a supply voltage range of 2.3V to 5.5V and offers a low on-resistance of 0.2Ω. It includes a 14ms blanking time to ensure transient voltages settle before current limiting activates. The component is housed in a compact SOT-23-5 package.

Current Regulation/Management Feature Summary

• Internal current limiting prevents damage to host devices due to faulty load conditions
• Low 0.2Ω on-resistance for efficient power distribution
• Guaranteed 14ms blanking time ensures transient voltages settle before activation

Current Regulation/Management Applications

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

Current Regulation/Management Procurement Notes

Verify the specific suffix (V or UK) against the manufacturer's official documentation to confirm pinout and package compatibility. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Ensure the selected variant matches the required 200mA current limit specification for the target application.

Current Regulation/Management Selection Notes

Select this component when a fixed 200mA current limit is required for protecting sensitive loads. Consider the 0.2Ω on-resistance impact on power dissipation at full load. Verify that the 2.3V to 5.5V input voltage range aligns with the system power supply. The SOT-23-5 package is suitable for space-constrained designs.

Current Regulation/Management Part Context

The MAX4915AEUK/V+T belongs to the MAX4914B/MAX4915A/B/MAX4917A/B family of current-limit switches. This family provides integrated protection for various load types with different current ratings (100mA, 200mA, 300mA). The MAX4915A specifically targets applications needing a 200mA limit, distinguishing it from the 100mA MAX4914B and 300mA MAX4917A variants.

Current Regulation/Management Replacement Considerations

Direct substitutes within the same family include the MAX4914BEUK+T (100mA limit) and MAX4917BEUK+T (300mA limit), provided the current rating adjustment is acceptable for the design. Ensure the replacement part maintains the same SOT-23-5 package and electrical characteristics.
