XC8109BD10ER-G

Overview

The XC8109BD10ER-G is a high-side power switch IC from Torex Semiconductor, designed for power distribution applications. It features a P-channel output with a maximum continuous output 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. Key timing parameters include a maximum turn-on time of 1 ms and a maximum turn-off time of 130 us. It is housed in a compact 6-USPC (1.8x2 mm) package and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Integrates adjustable current limiting functionality for precise load protection
• Includes comprehensive fault protection mechanisms such as over-temperature shutdown and reverse current blocking
• Features controlled slew rate to minimize inrush current during switching events

Applications

• Power distribution networks in portable electronic devices
• Load switching for USB peripheral interfaces
• Battery-powered system power management

Procurement Notes

Verify the specific suffix ER-G against the manufacturer's official datasheet to confirm packaging details and compliance status. Ensure the ordering information matches the required pin configuration and thermal characteristics for your PCB layout. Cross-reference the part number with authorized distributors to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when a high-side switch with integrated current limiting and thermal protection is required. The fixed current limit of 1.3 A suits loads up to 900 mA continuous operation. Consider the 6-USPC package size for space-constrained designs. Verify that the 2.5 V to 5.5 V input range aligns with the system power supply rails and that the logic interface requirements are met by the non-inverting input type.

Part Context

This part belongs to the XC8109 series of power switches from Torex Semiconductor. The series offers various configurations including adjustable current limits and different output currents. The XC8109BD10ER-G specifically denotes the version with fixed current limiting and the USP-6C package. It is part of Torex's portfolio aimed at providing efficient power management solutions for mobile and consumer electronics.

Replacement Considerations

Direct substitutes may include other XC8109 variants with similar current ratings but verify if the current limit type (fixed vs. adjustable) matches the design requirements. Check pin-to-pin compatibility with packages like 6-UFDFN. Ensure replacement parts support the same voltage range and thermal performance specifications.

FAQ

What is the maximum continuous output current for the XC8109BD10ER-G?

The maximum continuous output current is 900 mA.

Does the XC8109BD10ER-G support reverse current flow?

No, the device includes reverse current protection to prevent backflow.

What is the typical response time for over-temperature protection?

The datasheet specifies over-temperature shutdown as a feature, but exact response times are typically defined by the thermal characteristics and junction temperature thresholds rather than a fixed electrical delay parameter.
