TCK112G,LF

Overview

The TCK112G,LF is a single-channel high-side power switch IC manufactured by Toshiba Semiconductor and Storage. It features an N-channel output capable of delivering a maximum continuous current of 3A with a typical on-resistance of 8.3 milliohms. The device operates within a load voltage range of 1.1V to 5.5V and requires no separate supply voltage. Key electrical characteristics include non-inverting input logic and integrated fault protection against over-temperature conditions and reverse current. It is housed in a compact 6-WCSPC package measuring 1.5x1.0mm and supports an operating temperature range from -40°C to 85°C.

Feature Summary

• Integrates controlled slew rate functionality to minimize inrush current during turn-on events.
• Includes dedicated load release capability for safe discharge of capacitive loads upon shutdown.
• Provides comprehensive fault protection mechanisms including thermal shutdown and reverse current blocking.

Applications

• Power distribution networks in portable electronic devices requiring low profile components
• Load switching for peripheral circuits in mobile communication equipment
• High-side switching applications in automotive infotainment systems

Procurement Notes

Verify the specific suffix and tape-and-reel specifications when ordering, as packaging variants may differ. Confirm that the 6-WCSPC footprint matches your PCB layout constraints precisely. Ensure compatibility with the required input logic levels for your control interface. Check for any recent product change notices regarding material composition or manufacturing site updates.

Selection Notes

Select this component when a low on-resistance N-channel switch is needed for currents up to 3A in space-constrained designs. It is suitable for applications requiring precise control of turn-on speed to reduce electromagnetic interference. Consider the 1.1V minimum operating voltage to ensure compatibility with low-voltage logic systems. Evaluate the thermal performance requirements given the small package size and expected power dissipation under load.

Part Context

This part belongs to the TCK112 series of power management ICs designed for efficient power distribution. It serves as a direct replacement for discrete MOSFET solutions where board space is limited. The device integrates control logic and protection features typically found in larger packages into a miniature form factor.

Replacement Considerations

TCK111G,LF is documented as a parameter-equivalent substitute offering similar 3A current handling and low on-resistance characteristics in the same package type.
