Low resistance 10A power switch has accurate current sensing built-in

Silego Technology’s 2.0 x 3.0 mm CurrentPAK SLG6M6001V enables high accuracy current measurement in a configurable and programmable 10A, 3.8 mΩ RDS(ON) load switch.

CurrentPAK is a family of configurable mixed-signal ICs, or CMICs. A high performance load switch that has efficient, high accuracy current measurement, CurrentPAK is claimed as the first load switch to have advanced programmable features. Using non-volatile memory (NVM), designers can control several aspects of the device including enable logic, slew rate, current limiting, over-temperature protection, and integrated discharge rate.

“The ability to measure instantaneous power consumption is a given in today's high performance computation and telecommunications equipment,” said John McDonald, VP of Marketing. McDonald continued, “The designers of these systems need to provide a mechanism to report current consumption for intelligent power and thermal management. Typically, designers will use an external sense resistor to measure current consumption. This has the unfortunate side effect of significantly decreasing system power efficiency. Using CurrentPAK in this same application, the current sense resistor and other external components are eliminated, thereby reducing cost and making CurrentPAK the highest efficiency solution in its class.”

The first device in the CurrentPAK family, the SLG6M6001V, has a current rating of 10A continuous, an ultra-low RDS(ON) value (3.8 mΩ), and comes in a 2.0 x 3.0 mm, fully encapsulated, plastic package.
