TCK101G,LF

Overview

The TCK101G,LF is a single-channel high-side power switch manufactured by Toshiba Semiconductor and Storage. It utilizes a P-channel MOSFET configuration to manage load currents up to 1A within a 1.1V to 5.5V supply range. The device operates without an external supply voltage (Vcc/Vdd), simplifying circuit design. It features a compact 6-WCSP package with dimensions of 1.5x1.0mm. Key electrical characteristics include a typical on-resistance of 8.3 milliohms and non-inverting input logic. The component supports surface mount installation and functions reliably across an ambient temperature range of -40°C to 85°C.

Feature Summary

• Integrates a P-channel power switch for high-side load control without requiring separate supply voltage.
• Includes built-in protection mechanisms against over-temperature conditions and reverse current flow.
• Utilizes a minimal footprint 6-WCSP package suitable for space-constrained surface-mount applications.

Applications

• General-purpose power distribution in portable electronic devices
• Load switching for peripheral circuits in consumer electronics
• Battery-powered system power management

Procurement Notes

Verify the specific ordering suffix and tape/reel specifications when sourcing components. Confirm that the received parts match the manufacturer's part number TCK101G,LF exactly. Ensure compliance with RoHS standards as indicated by the LF designation. Check datasheet revisions for any updates to mechanical drawings or electrical limits prior to integration into final designs.

Selection Notes

Select this component for applications requiring simple high-side switching with low on-resistance. It is suitable for loads operating between 1.1V and 5.5V. Consider the 1A current limit and thermal performance when designing heat dissipation paths. The non-inverting input allows direct connection to standard logic levels. Evaluate the 6-WCSP package size against available board space constraints.
