Texas Instruments has introduced a single-chip eFuse with back-to-back FETs, providing a high rating of protection at up to 60V. The TPS2660 is the most integrated eFuse on the power management market for 24V and 48V rail applications in industrial, automotive and communication infrastructure designs, according to the company.

The device enables reverse polarity protection to help guard the system load from miswiring, which can occur in industrial equipment that use screw terminals, while reverse current blocking prevents current from flowing backward from the output side to the input side.

TPS2660 also features advanced protection and integration, reducing board space up to 40% by eliminating the need for external components. The device's adjustable overvoltage protection helps designers pass industry-standard surge-compliance tests more quickly and reliably, including the electrical fast transient (EFT) test.

The eFuse is available now in the TI store and through the company's authorised distribution network. The TPS2660 comes in a 4.4mm x 5mm thin shrink small outline package (TSSOP) and is priced at ₹146.66 ($2.20) in 1,000-unit quantities.
