Vishay Intertechnology eFuses Offer Wide 2.8 V to 23 V Operating Voltage Range With Active Reverse Blocking

17.03. 2023 | News

Vishay Intertechnology, Inc. 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 (more info).
