TCK1024G,LF

Overview

The TCK1024G,LF is a single-channel P-Channel power switch IC manufactured by Toshiba Semiconductor and Storage. It operates within a load voltage range of 1.4V to 5.5V and supports a maximum output current of 1.54A. The device features a typical on-resistance (Rds On) of 31mOhm and utilizes a non-inverting input interface for On/Off control. Packaged in a 6-UFBGA WLCSP format, it integrates high-side switching capabilities with comprehensive fault protection mechanisms.

Feature Summary

• Integrates fixed current limiting, over-temperature protection, and reverse polarity protection for robust circuit safeguarding.
• Includes built-in load discharge functionality to rapidly dissipate stored energy when the switch is turned off.
• Utilizes a compact WLCSP package design suitable for space-constrained portable electronic applications.

Applications

• Portable consumer electronics requiring efficient power distribution management
• Battery-powered devices needing high-side load switching solutions
• Systems requiring protection against over-current and thermal faults

Procurement Notes

Verify the complete part number including the LF suffix to ensure compliance with lead-free manufacturing standards. Confirm the specific tape and reel packaging configuration required for your automated assembly line. Cross-reference the datasheet revision date to ensure compatibility with your system's electrical specifications and thermal requirements before finalizing procurement orders.

Selection Notes

Select this component when a low-profile, single-channel high-side switch is required for voltages between 1.4V and 5.5V. The 31mOhm on-resistance makes it suitable for applications prioritizing power efficiency and minimal voltage drop. Ensure the operating temperature range of -40°C to 85°C aligns with your environmental conditions and that the WLCSP package fits your PCB footprint constraints.

Part Context

This component belongs to Toshiba's series of integrated load switches designed for portable electronics. It serves as a critical power management element, replacing discrete MOSFET solutions to save board space. The integration of protection features reduces the need for external components, simplifying the overall circuit design while enhancing reliability in mobile and handheld device architectures.

Replacement Considerations

Consult official Toshiba documentation for verified substitute part numbers. Do not assume cross-compatibility with other manufacturers' pinouts or electrical characteristics without rigorous validation. Verify that any alternative component matches the 6-UFBGA WLCSP package dimensions and thermal performance requirements.
