4.5-V to 60-V, 31mΩ, 0.6-6A eFuse with output power limiting

The TPS1663x is an easy-to-use,

positive 60V, 6A eFuse with a 31mΩ 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 4mm ×

4mm 24-pin VQFN package and are specified over a –40°C to +125°C temperature

range.
