XC8109BC10ER-G

Overview

The XC8109BC10ER-G is a high-side power distribution switch manufactured by Torex Semiconductor Ltd. It features a single P-channel output with a maximum continuous current of 900 mA and a fixed current limit of 1.3 A. The device operates within a supply voltage range of 2.5 V to 5.5 V and exhibits a maximum on-resistance of 104 mOhms. It includes protection against over-current, thermal shutdown, and reverse current. The component supports controlled slew rates and status flags, functioning within an operating temperature range of -40°C to +105°C in a USP-6C surface-mount package.

Feature Summary

• High-side P-channel power switch configuration for load distribution
• Integrated adjustable current limiting and thermal shutdown protection
• Controlled slew rate functionality to minimize inrush current
• Status flag output for monitoring operational state

Applications

• USB port power switching and distribution
• Battery-powered portable electronic devices
• Load switching in mobile communication equipment
• Power management circuits requiring reverse current protection

Procurement Notes

Verify the specific suffix 'BC10' against the official Torex datasheet to confirm the exact current limit and resistance parameters, as variations exist within the XC8109 series. Ensure the USP-6C package footprint matches the design layout. Confirm RoHS compliance status directly from the manufacturer's certification documents prior to final procurement approval.

Selection Notes

Select this component when a high-side switch with integrated current limiting and reverse current protection is required for low-voltage applications. The USP-6C package offers a compact solution for space-constrained designs. Consider the 104 mOhm on-resistance for power dissipation calculations and verify that the 900 mA output current meets the load requirements without exceeding the 1.3 A limit threshold.

Part Context

The XC8109BC10ER-G belongs to the XC8109 series of power switch ICs designed for power distribution tasks. This series is characterized by its CMOS technology, which enables low power consumption and high reliability. The device integrates multiple protection features typical of modern load switches, making it suitable for applications where system integrity and component safety are critical under fault conditions.

Replacement Considerations

Consult the official Torex XC8109 series documentation for verified substitute part numbers. Cross-reference pinouts and electrical specifications carefully before substituting.
