XC8107BC15MR-G

Overview

The XC8107BC15MR-G is a high-side power switch IC from Torex Semiconductor, designed for power distribution applications. It features a fixed current limit of 1.9 A with a typical output current capability of 1.5 A. The device operates within a supply voltage range of 2.5 V to 5.5 V and exhibits a maximum on-resistance of 120 mOhms. Key timing parameters include a maximum turn-on time of 1 ms and a maximum idle time of 130 us. The component supports a power dissipation of 250 mW and functions reliably across an operating temperature range of -40°C to +105°C. It is housed in a compact SOT-25-5 surface-mount package.

Feature Summary

• Integrates fixed current limiting protection to safeguard connected loads against overcurrent conditions.
• Provides high-side switching capability with low on-resistance for efficient power distribution.
• Features controlled turn-on and idle timing characteristics to manage inrush currents and system sequencing.

Applications

• Power distribution networks in portable electronic devices
• Load switching for peripheral modules in mobile communications equipment
• Overcurrent protection circuits in industrial control systems

Procurement Notes

Verify the specific suffix MR-G confirms the reel packaging format and RoHS compliance status prior to ordering. Ensure the design accommodates the 120 mOhm maximum on-resistance to meet thermal and voltage drop requirements at full load. Confirm that the 1.9 A fixed current limit aligns with the protected circuit's fault tolerance specifications. Validate that the SOT-25-5 footprint matches the PCB layout constraints.

Selection Notes

Select this component when a single-channel high-side switch with integrated fixed current limiting is required. The 1.5 A output rating and 120 mOhm resistance make it suitable for moderate load applications. Consider the 1 ms turn-on time for applications where soft-start behavior is necessary to prevent voltage sag. The wide operating temperature range supports use in demanding environmental conditions compared to standard commercial-grade switches.

Part Context

This part belongs to the XC8107 series of high-function power switches from Torex Semiconductor. The series offers various output current ratings and on-resistance values to suit different load requirements. The BC15 variant specifically denotes the 1.5 A output and 1.9 A current limit configuration within this family of power distribution ICs.

Replacement Considerations
