MAX4787EXK+TC7Q

Current Regulation/Management Overview

The MAX4787EXK+TC7Q is a current-limiting switch manufactured by Analog Devices Inc./Maxim Integrated. It operates within an input voltage range of 2.3V to 5.5V, supporting compatibility with 3.3V systems. The device provides output current limiting options of 50mA and 100mA. It is housed in a compact SC-70-5 package, also identified as 5-TSSOP or SOT-353. This component functions as a power distribution switch designed to protect downstream circuits from overcurrent conditions.

Current Regulation/Management Feature Summary

• Provides precise current limiting for load protection
• Operates with standard 3.3V system voltages
• Utilizes a compact surface-mount package

Current Regulation/Management Applications

• Portable electronic devices requiring overcurrent protection
• Peripheral circuitry in 3.3V logic systems
• Power distribution networks needing current regulation

Current Regulation/Management Procurement Notes

Verify the specific suffix TC7Q against official Analog Devices documentation to confirm tape-and-reel packaging and RoHS compliance status. Ensure the selected variant matches the required current limit specification. Cross-reference the SC-70-5 footprint with PCB design files to guarantee mechanical compatibility before finalizing procurement orders.

Current Regulation/Management Selection Notes

Select this component when designing circuits that require integrated current limiting without external sensing resistors. Consider the SC-70-5 package size constraints and the 2.3V to 5.5V input voltage window. Evaluate whether the fixed 50mA or 100mA limit aligns with the target load requirements and system safety margins.

Current Regulation/Management Part Context

This part belongs to the MAX4787 family of current-limiting switches from Maxim Integrated. These devices are engineered for portable applications where space is limited and reliable power management is critical. The series typically offers various current thresholds and package options to suit different design constraints.

Current Regulation/Management Replacement Considerations

Consult official substitution guides for equivalent current-limiting switches in similar packages. Verify pinout compatibility and electrical specifications before replacing with alternative manufacturers' components.
