Toshiba launches four compact eFuse chips for low-voltage power lines
Toshiba has launched four electronic fuse chips called the TCKE5 Series.
The products come from Toshiba Electronic Devices & Storage Corporation in Japan.
They are designed to protect power supply lines from overcurrent and short circuits.
Their input voltage range is 1.7V to 5.5V, including the 1.8V lines used in some electronic equipment.
The chips are housed in a small SOT-353F package.
Smaller devices and lower power use have increased the need for protection that works with low-voltage supplies.
The new products are intended to help improve the reliability of those systems, and shipments have started.
