TCK106AF,LF

Overview

The TCK106AF,LF is a single-channel high-side load switch manufactured by Toshiba Semiconductor and Storage. It operates within a supply voltage range of 1.1 V to 5.5 V and supports an output current of 1 A. The device features a maximum on-resistance of 90 mΩ, with a typical turn-on time of 100 µs and a turn-off time of 10 µs. It functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides high-side power switching capability for single-channel distribution
• Integrates low on-resistance for efficient power delivery
• Supports controlled turn-on and turn-off timing characteristics

Applications

• Power distribution in portable electronic devices
• Load switching in automotive infotainment systems
• Peripheral power management in industrial control equipment

Procurement Notes

Verify the specific suffix LF for lead-free compliance against project requirements. Confirm package availability matches design constraints. Ensure input voltage levels remain within the 1.1 V to 5.5 V operational window. Validate thermal performance under maximum load conditions at elevated temperatures.

Selection Notes

Select this component when a single-channel high-side switch with 1 A capacity is required. Compare on-resistance values against alternative models like the TCK106AG if lower resistance is critical. Consider turn-on speed requirements relative to system sensitivity. Evaluate package options based on PCB space limitations.

Part Context

This part belongs to Toshiba's TCK series of load switches designed for power distribution applications. It complements other variants such as the TCK106AG which offers different electrical characteristics. The series targets compact designs requiring reliable high-side switching with minimal footprint.

Replacement Considerations

The TCK106AG,LF serves as a verified substitute offering lower on-resistance but slower turn-on times. Verify pin compatibility and thermal performance before substitution.
