MAX4917AELT+T

Current Regulation/Management Overview

The MAX4917AELT+T is a current-limit switch from the MAX4917 family, manufactured by Analog Devices Inc./Maxim Integrated. It offers selectable output current limits of 100mA, 200mA, or 300mA. The device operates within an input voltage range of 2.3V to 5.5V and supports an operating temperature range of -40°C to +85°C. It utilizes a 6-pin Ultra Thin Dual Flat No-Lead (UTDFN) package with dimensions of approximately 2mm x 2mm. Key electrical characteristics include low shutdown reverse current and integrated fault protection.

Current Regulation/Management Feature Summary

• Provides selectable current limiting thresholds for precise load protection
• Features low shutdown reverse current to prevent back-feeding in powered-off states
• Integrates comprehensive fault protection mechanisms including overcurrent and thermal shutdown

Current Regulation/Management Applications

• Portable electronic devices requiring efficient power distribution
• Peripheral port protection in computing systems
• Battery-powered equipment needing controlled current delivery

Current Regulation/Management Procurement Notes

Verify the specific suffix 'LT' corresponds to the UTDFN-6 package variant when sourcing. Confirm RoHS compliance status as indicated by the '+' suffix. Ensure the selected component matches the required current limit configuration for your design. Cross-reference the manufacturer's latest documentation for any end-of-life notices or obsolescence warnings associated with this part number.

Current Regulation/Management Selection Notes

Select this component when a compact solution for current-limited power switching is required. The UTDFN-6 package suits space-constrained designs. Consider the 2.3V minimum input voltage for compatibility with single-cell lithium battery applications. Evaluate the trade-off between the three available current limit options against the maximum load requirements of the target circuit.

Current Regulation/Management Part Context

This part belongs to the MAX4917 series of current-limit switches designed for portable electronics. It serves as a power distribution element that protects downstream loads from excessive current draw. The series is characterized by its small footprint and ability to operate efficiently across standard low-voltage digital logic levels.
