TCK111G,LF

Overview

The TCK111G,LF is a single-channel high-side power distribution switch manufactured by Toshiba Semiconductor and Storage. It utilizes an N-channel MOSFET to manage load connections within electronic systems. The device supports a load voltage range of 1.1V to 5.5V and delivers a maximum output current of 3A. Key electrical characteristics include a typical on-resistance of 8.3 milliohms and a non-inverting open/switch interface. Integrated protection mechanisms provide fault handling for over-temperature conditions and reverse current scenarios. The component operates reliably across a temperature range of -40°C to +85°C and is housed in a compact 6-WCSPC package measuring 1.5x1.0 mm.

Feature Summary

• Integrates controlled slew rate functionality to minimize inrush current during turn-on events
• Provides comprehensive fault protection against over-temperature conditions and reverse current flow
• Features a non-inverting input interface for straightforward logic control integration

Applications

• Portable consumer electronics requiring efficient power distribution management
• Industrial equipment utilizing low-voltage DC power architectures
• Automotive subsystems operating within specified thermal and voltage constraints

Procurement Notes

Verify the specific ordering suffix when sourcing components, as variations such as LF(S) may indicate distinct packaging formats like cut tape or reel without altering the core semiconductor function. Confirm RoHS compliance status through official manufacturer documentation prior to finalizing procurement contracts. Ensure that the selected supplier provides valid traceability data consistent with Toshiba Semiconductor and Storage quality standards.

Selection Notes

Select this component for applications requiring a high-current single-channel switch with integrated reverse current protection. The N-channel configuration offers lower on-resistance compared to P-channel alternatives, improving efficiency in low-voltage systems. Consider the 6-WCSPC package dimensions for space-constrained PCB layouts. Evaluate the thermal performance requirements against the device's operational limits to ensure reliable long-term operation under varying load conditions.
