Toshiba Launches New Series of eFuse ICs, Electronic Fuses That Can Be Used Repeatedly
Toshiba Electronic Devices & Storage Corporation (“Toshiba”)
has launched a line-up of eight compact, high-voltage electronic fuses (eFuse
ICs), the TCKE9 Series, that support multiple functions for the protection of
power supply lines. Shipments of the first two products “TCKE903NL”
and “TCKE905ANA”
start today, with others to follow.
The
TCKE9 Series products have a current limit and voltage clamp function to
protect the lines in power supply circuits against overcurrent and overvoltage
conditions, something that standard physical fuses cannot do. Even in the event
of abnormal overcurrent or overvoltage, the specified current and voltage are
maintained.
The
new products also feature over-temperature protection and short-circuit
protection, which protects a circuit by immediately shutting off the eFuse IC
when abnormal heat is generated in the circuit or an unexpected short-circuit
occurs. A further eFuse IC advantage is the elimination of complex circuit
design and a reduced component count, realizing much simpler circuit designs
with fewer components and a smaller area than is possible with a protection
function secured with discrete parts.
Toshiba
intends to obtain IEC 62368-1 certification, the international safety standard
for high level safety, for the eFuse ICs, which will also simplify
certification tests customers’ devices are required to undergo.
The
product lineup offers eight products: four, 3.3V, 5V, 12V, 20V, are suitable
for overvoltage protection of a range of power supply voltages, and each has
two types – an auto-retry type, where the eFuse IC automatically recovers the
circuit itself, and a latch type, where recovery is triggered by an external
signal. Customers can select the appropriate product for their requirements and
the size of their equipment.
