Load Switch ICs

The load switch IC is a power supply IC fabricated using CMOS processes and featuring built-in output transistors and output drivers. Compared with the conventional discrete configuration, this system is greatly reduced in size. It also features low-voltage operation, low-on-resistance characteristics, and low current consumption, and is equipped with various additional functions. The package lineup focuses on ultra-small products of the 1 mm2 class. In particular, the package lineup provides products that are suitable for use in portable devices that require space saving.

Smaller Area and Higher Functionality
Toshiba Load Switch ICs have various additional functions that are complicated with the conventional circuit configuration configured with discrete components, such as inrush current reduction, reverse current blocking, overcurrent protection, thermal shutdown, and auto output discharge, in a single-chip IC. They easily realize high-performance systems with a small area and at low cost.
