XC8107BC20ER-G

Overview

The XC8107BC20ER-G is a single-channel load switch manufactured by Torex Semiconductor. It operates within an input voltage range of 2.5 V to 5.5 V and supports a maximum output current of 2 A. The device features a fixed current limit set at 2.4 A and a typical on-resistance of 85 mΩ, with a maximum specification of 120 mΩ. Key timing parameters include a maximum turn-on time of 1 ms and a maximum idle time of 130 µs. The component is housed in a SOT-25-5 package and functions reliably across an operating temperature range from -40°C to +105°C.

Feature Summary

• Integrates a fixed current limit circuit to protect against overcurrent conditions without requiring external sensing components.
• Provides controlled ramp-up functionality to manage inrush currents during power-up sequences.
• Features low on-resistance characteristics to minimize power loss and voltage drop during conduction.

Applications

• Power distribution networks in portable electronic devices
• Load switching for peripheral circuits in mobile phones
• Power management sections in consumer electronics

Procurement Notes

Verify the specific suffix 'ER' against official documentation to confirm the tape and reel packaging configuration and quantity per reel. Ensure the part number matches the exact electrical specifications required for the target application, particularly the current limit and on-resistance values. Cross-reference the manufacturer's latest datasheet to confirm compliance with environmental standards such as RoHS before finalizing procurement orders.

Selection Notes

Select this component when a single-channel power switch with integrated fixed current limiting is required for voltages up to 5.5 V. The choice is appropriate for applications needing precise inrush current control and protection against short circuits. Consider the thermal performance and package size relative to the expected load current and ambient temperature constraints of the design.

Part Context

This part belongs to the XC8107 series of high-function power switches designed by Torex Semiconductor. The series focuses on providing robust protection features within a compact footprint suitable for space-constrained modern electronics. The XC8107BC20 variant specifically denotes the electrical characteristics and pin configuration unique to this model within the broader product family.

Replacement Considerations

Consult the official Torex Semiconductor cross-reference data or equivalent product selection guides to identify verified substitute part numbers. Do not assume functional compatibility based solely on package similarity; verify electrical parameters such as current limit thresholds and on-resistance values against the original specifications.
