TPS2660x Industrial eFuses

Texas Instruments offers its TPS2660x, 60 V, 2 A, industrial eFuses with integrated reverse-input polarity protection

Image of Texas Instruments' TPS2660x Industrial eFusesTexas Instruments' TPS2660x devices are compact, feature-rich, high-voltage eFuses with a full suite of protection features. The wide supply input range of 4.2 V to 55 V allows control of many popular DC bus voltages. The device can withstand and protect the loads from positive and negative supply voltages up to ± 60 V. Integrated back-to-back FETs provide a reverse current blocking feature, making the device suitable for systems with output voltage holdup requirements during power-fail and brownout conditions. Load, source, and device protection are provided with many adjustable features including over-current and output slew rate as well as over-voltage, and under-voltage thresholds. The internal robust protection control blocks, along with the high-voltage rating of the TPS2660x, help to simplify the system designs for surge protection.

A shutdown pin provides external control for enabling and disabling the internal FETs as well as placing the device in a low current shutdown mode. For system status monitoring and downstream load control, the device provides fault and precise current monitor output. The MODE pin allows flexibility to configure the device between the three current-limiting fault responses (circuit breaker, latch off, and auto-retry modes).

The devices are available in a 5 mm x 4.4 mm, 16-pin HTSSOP as well as a 5 mm x 4 mm, 24-pin VQFN package and are specified over a -40°C to 125°C temperature range.
