Overview
The TCK22892G,LF is a high-side power switch IC from Toshiba Semiconductor and Storage designed for load distribution applications. It operates within a supply voltage range of 1.4V to 5.5V and supports an output current of 740mA. The device features a maximum on-resistance of 140mΩ, with a typical turn-on time of 40μs and a turn-off time of 10μs. It is housed in a WCSP-6 package and functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- High-side switching capability for efficient load distribution
- Low on-resistance for minimized power loss
- Controlled slew rate to reduce electromagnetic interference
Applications
- Load distribution in portable electronic devices
- Power management in automotive infotainment systems
- Industrial equipment peripheral power control
Procurement Notes
Verify the specific suffix 'LF' indicates lead-free compliance as per manufacturer standards. Confirm the WCSP-6 package dimensions match your PCB footprint requirements. Ensure the input voltage does not exceed the 5.5V absolute maximum rating during operation. Check for any specific handling instructions regarding electrostatic discharge sensitivity associated with this component type.
Selection Notes
Select this component when a compact high-side switch with moderate current capacity is required. The low on-resistance makes it suitable for battery-powered applications where efficiency is critical. Consider the WCSP-6 package size constraints against available board space. Verify that the 740mA output current meets the peak load requirements of the connected circuitry without triggering thermal protection.
Part Context
This part belongs to Toshiba's TCK series of power switches, which are integrated circuits designed to replace discrete MOSFET solutions. These ICs offer built-in protections and controlled switching characteristics, simplifying design while reducing component count. The series targets applications requiring reliable power management in space-constrained environments.
Replacement Considerations
Consult official Toshiba documentation for verified cross-reference part numbers. Do not assume functional equivalence with other manufacturers' parts without verifying pinout, electrical parameters, and package compatibility.
