Vishay Intertechnology eFuses Offer Wide 2.8 V to 23 V Operating Voltage Range With Active Reverse Blocking
January 11 2023 - 11:00AM
Vishay Intertechnology, Inc. (NYSE: VSH) today introduced four new
eFuses that feature programmable current limits and overvoltage
protection (OVP) in the compact 3 mm by 3 mm TDFN package. Designed
to operate over a wide 2.8 V to 23 V input voltage range — with a
28 VIN DC tolerance — the 3.5 A SiP32433A/B and 6 A SiP32434A/B
integrate multiple control and protection features to simplify
designs and minimize the need for external components.
While most competing solutions only offer voltages to 18 V, or
are missing their low voltage side, the input voltage range of the
Vishay Siliconix single-channel load switches released today allows
them to be used in a wider range of designs. The devices are
intended for industrial and medical equipment, robotics, consumer
goods, home automation systems, and gaming consoles, where they
provide precise control and swift fault responses to enhance the
safety and reliability of system designs. Upon switch-off due to
latchable faults in these applications, the SiP32433A and SiP32434A
are designed to latch the power switch off, while the SiP32433B and
SiP32434B will auto-retry after a settable period of time.
All four devices respond swiftly to short circuits, and their
precise overcurrent protection (OCP) is triggered at a set current
limit level without an excessive overhead current requirement — an
important characteristic for designs in which power busses need to
support multiple loads. Competing solutions often require overhead
currents of more than 30 %. The SiP32433A and SiP32433B with active
reverse blocking target applications featuring USB Type-C and
multiple power source switching.
The load switches reduce on-resistance by 43 % compared to
previous-generation solutions, which translates into a 32 % higher
current capability or increased efficiency at the same current
level. The 78 mΩ SiP32433A/B has a current limit setting range of
0.3 A to 3.5 A, while the 33 mΩ SiP32434A/B offers a range of 0.5 A
to 6 A. Both devices guarantee current limit accuracy down to
± 8 %, increase design flexibility, and simplify BOMs.
The hot-swappable load switches feature a programmable turn-on slew
rate, provide ESD tolerance of 2 kV (human body model) and 0.75 kV
(charged device model), and operate over a temperature range of -40
°C to +125 °C.
Samples and production quantities of the eFuses are available
now, with lead times of 20 weeks.
