TCK22974G,LF

Overview

The TCK22974G,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 a maximum continuous output current of 2 A. The device features a typical on-resistance of 185 mOhms and dissipates up to 800 mW of power. Electrical characteristics include a maximum turn-on time of 2 ms and a maximum turn-off time of 10 us. It functions reliably across an ambient temperature range of -40°C to +85°C and is housed in a compact WCSP-6 package.

Feature Summary

• Integrates a single high-side power switch for efficient load distribution
• Provides comprehensive protection against over-temperature conditions and under-voltage lockout
• Supports rapid switching transitions with controlled rise and fall times

Applications

• Power distribution networks in portable electronic devices
• Load switching in consumer electronics systems
• Battery-powered equipment requiring efficient power management

Procurement Notes

Verify the specific ordering suffix and packaging configuration when sourcing components. Confirm that the received parts match the exact manufacturer part number and package type specified in the design requirements. Ensure compliance with RoHS standards and check for any relevant environmental certifications required for the target application market before finalizing procurement orders.

Selection Notes

Select this component when a single-channel high-side switch is required for low-voltage applications. The 2 A current capability and low on-resistance make it suitable for driving moderate loads efficiently. Consider the WCSP-6 package size for space-constrained designs. Evaluate the thermal performance based on the 800 mW power dissipation rating relative to the expected operating environment and PCB layout constraints.

Part Context

This load switch belongs to Toshiba's series of power distribution ICs designed for modern electronic systems. These components integrate protection features typically found in more complex smart switches but in a simplified, cost-effective format. The TCK22974G,LF complements other similar devices like the TCK22971G,LF and TCK22973G,LF, offering consistent performance metrics within the family while maintaining distinct operational parameters for system designers.

Replacement Considerations

The TCK22971G,LF and TCK22973G,LF are confirmed substitutes within the same product family. Verify compatibility regarding switching speed differences, as the TCK22971G,LF exhibits faster turn-on characteristics compared to the TCK22974G,LF.
