XC8107BC05MR-G

Overview

The XC8107BC05MR-G is a high-function power switch IC manufactured by Torex Semiconductor Ltd. It operates as a high-side switch with a fixed current limit feature, designed for power distribution applications. The device supports an input voltage range of 2.5 V to 5.5 V and delivers a maximum output current of 2 A. Key electrical parameters include a maximum on-resistance of 120 mOhms, a typical turn-on time of 1 ms, and a maximum turn-off time of 130 us. It functions within a supply voltage range up to 5.5 V and is rated for operation between -40°C and +105°C. The component is housed in a compact SOT-25-5 surface-mount package.

Feature Summary

• Integrates a high-side power switch with built-in fixed current limiting protection
• Provides fast switching performance with controlled turn-on and turn-off times
• Supports wide operating temperature ranges suitable for industrial environments

Applications

• Power distribution systems requiring overcurrent protection
• High-side load switching in portable electronic devices
• Peripheral power control in automotive electronics

Procurement Notes

Verify the specific suffix 'BC' against official Torex documentation to confirm the exact output voltage threshold or current limit setting, as these variants often differ slightly despite shared base model numbers. Ensure the ordering code matches the required thermal and electrical specifications for your target application environment. Cross-reference the datasheet revision date to guarantee compatibility with current manufacturing standards and pinout configurations.

Selection Notes

Select this component when a robust high-side switch with inherent current limiting is required for loads up to 2 A. The fixed current limit simplifies design by removing external sensing components. Consider the 120 mOhm on-resistance for power loss calculations and ensure the 130 us turn-off time meets system timing requirements. Verify that the 5.5 V maximum input rating aligns with the source voltage rails available in the circuit design.

Part Context

This part belongs to the XC8107 series of high-function power switches from Torex Semiconductor. The series is characterized by low on-resistance and integrated protection features such as current limiting and thermal shutdown. These ICs are designed to replace mechanical relays and discrete transistor solutions, offering smaller footprint and higher reliability in modern power management architectures.

Replacement Considerations

Consult official Torex cross-reference lists for direct replacements. Generic equivalents may lack the specific fixed current limit characteristics or the precise turn-on/turn-off timing profiles documented for this model.
