MAX4786EXS+T

Current Regulation/Management Overview

The MAX4786EXS+T is a single-channel power distribution switch IC manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 2.3 V to 5.5 V and features an adjustable current limit with selectable options of 50 mA or 100 mA. The device includes a fixed output current limit of 20 mA for protection. Key electrical parameters include a maximum on-resistance of 1 Ohm, a maximum turn-on time of 50 µs, and a maximum idle time of 30 ns. It supports a maximum power dissipation of 245 mW and functions across an operating temperature range from -40°C to +85°C.

Current Regulation/Management Feature Summary

• Provides precise current limiting with selectable thresholds to protect downstream loads from overcurrent conditions.
• Integrates fast switching capabilities with defined turn-on and idle times for responsive power management.
• Offers low on-resistance characteristics to minimize power loss during conduction.

Current Regulation/Management Applications

• Power distribution in portable electronic devices requiring compact current protection
• Peripheral circuit protection in consumer electronics systems
• Battery-powered equipment needing efficient power switching

Current Regulation/Management Procurement Notes

Verify component authenticity through authorized distributors due to limited availability status. Confirm RoHS compliance documentation matches the specific batch. Ensure the SC-70-4 package variant aligns with PCB footprint requirements. Check for end-of-life notifications as supply may be restricted. Validate datasheet revisions against design specifications before integration.

Current Regulation/Management Selection Notes

Select this component when a single-channel switch with adjustable current limits between 50 mA and 100 mA is required. Consider the 1 Ohm on-resistance for thermal management in space-constrained designs. Verify that the 2.3 V to 5.5 V input range matches the system power rail. Evaluate the 50 µs turn-on time against signal integrity requirements for sensitive loads.

Current Regulation/Management Part Context

This part belongs to the MAX4788 series family of current-limit switches, designed for power distribution applications. It shares functional similarities with other Maxim Integrated power switches but offers specific current limit configurations. The SC-70-4 package provides a small form factor suitable for dense PCB layouts in modern electronic devices.
