The TPS1663x is an easy to use, positive 60 V, 6-A eFuse with a 31-mΩ integrated FET. Protection for the load, source and eFuse itself are provided along with adjustable features such as accurate overcurrent protection, fast short circuit protection, output slew rate control, overvoltage protection and undervoltage lockout. The TPS16332 device integrates adjustable output power limiting (PLIM) functionality that simplifies and enables compliance to standards such as IEC61010-1 and UL1310. The device also includes adjustable overcurrent functionality. PGOOD can be used for enable and disable control of the downstream DC-DC converters.

A shutdown pin provides external control for enabling and disabling the internal FET 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 a precise current monitor output. The MODE pin allows flexibility to configure the device between the two current-limiting fault responses (latch off and auto-retry).

The devices are available in a 4-mm × 4-mm 24-pin VQFN package and are specified over a –40°C to +125°C temperature range.
