Power switches for high-current applications in ground vehicles introduced by Infineon Technologies
MUNICH – Infineon Technologies AG in Munich is introducing the Power PROFET + 12V switch family for modern electrical and electronic ground vehicles.
The PROFET + 12V power switches come in TO-leadless packages, and allow for mounting locations and enclosure options for a decentralized power architectures with high efficiency.
Two variants are available: the BTS50005-1LUA with an on-resistance (R DS(ON)) of 0.6 milliohms and the BTS50010-1LUA with an R DS(ON) of 1.0 milliohms for low power losses.
They are designed to control high-current applications, especially in hot cabin and engine compartments in demanding high-inrush currents, such as in heaters, pumps and fans. They provide more than 1 million switching cycles.
The switches can replace electromechanical relays, fuses, and discrete circuits in power-distribution boxes and other applications to 65 amps in a 12-volt electrical system.
The switches offer built-in protection and diagnostic functions like short-circuit, over-current and over-temperature protection. As a result, the devices provide a fault signal via the diagnosis enable pin to a connected microcontroller for advanced diagnosis in power distribution modules.
The smart power switches come in an 8-pin TO leadless package, and the accuracy of the load current sense has been improved down to 5 percent and can be evaluated by reading an analog voltage on the IS pin.
The switch family is PRO-SIL ISO 26262-ready and comes with a safety application note supporting the evaluation of hardware elements according to ISO 26262. For more information contact Infineon Technologies online at www.infineon.com.
