Overview
The TCK22971G,LF is a 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 continuous output current of 2 A. The device features a maximum on-resistance of 185 mOhms and dissipates up to 800 mW of power. Electrical timing specifications include a maximum turn-on time of 3 us and a maximum turn-off time of 10 us. It functions reliably across an operating temperature range from -40 C to +85 C and is housed in a WCSP-6 surface-mount package.
Feature Summary
- High-side power distribution with single-channel output
- Low on-resistance for efficient power delivery
- Fast switching response times
- Compact surface-mount packaging
Applications
- Power distribution in portable electronic devices
- Load switching in industrial control systems
- Power management in automotive electronics
Procurement Notes
Verify the complete part number including the LF suffix to ensure compliance with lead-free manufacturing standards. Confirm that the required output current does not exceed the 2 A limit under expected thermal conditions. Ensure the input voltage remains within the specified 1.1 V to 5.5 V range during operation. Check the datasheet for specific PCB layout recommendations to maintain signal integrity and thermal performance.
Selection Notes
Select this component when a compact high-side switch is needed for low-voltage applications. The 185 mOhm resistance offers a balance between size and conduction loss. Consider the WCSP-6 package for space-constrained designs. Compare against other TCK229xx variants if different switching speeds or resistance values are required for the specific circuit topology.
Part Context
This device belongs to the TCK229 series of load switches from Toshiba. The series includes variants with different on-resistances and switching speeds, such as the TCK22910G and TCK22974G. All share similar voltage ranges and packaging options, allowing for design flexibility while maintaining consistent interface characteristics across the product line.
Replacement Considerations
The TCK22974G,LF is a confirmed substitute within the same series. Verify compatibility regarding the 185 mOhm on-resistance and 2 A current rating. Ensure the replacement maintains the WCSP-6 footprint and electrical specifications for direct integration.
