About PROFET? +2 12V high-side smart power switch family
Infineon's PROFET? +2 12V family provides as a diagnostic feature an analog current sense with an outstanding accuracy (¡Ü 4 % at nominal load current). It can be used to monitor the application state as normal, overload, open load, short-circuit to ground, short-circuit to battery condition, protective switch off (overtemperature and overcurrent shutdown), protect the load and the wiring harness, and monitor the output current to control the output power.
The PROFET? +2 12V family offers two variants that differ in the protection strategy mechanism: intelligent restart control and intelligent latch. The first variant has an internal counter which counts the number of fault events (up to 7) before latching. The second variant has an internal latch which protects the output stage in case of a fault event. When the device latches, a reset can be applied to restart the counter.
PROFET? +2 12V design support
Infineon offers a range of design-in materials, which include application notes, evaluation boards, PCB design data, simulation models, and also online simulations. Those materials can be found on each product page in chapter "Design Support". In addition, we offer a dedicated tool suite for smart power switches and gate driver ICs for automotive power distribution.
Infineon's Smart Switches Tool Suite support system architects and hardware designers from the idea to the realization. This suite allows the user to select the right smart power switch for a specific load using one of the ¡°Finder & Selection¡± tools. Together with the different ¡°Simulation & Modeling¡± tools, various application scenarios can be simulated for the respective product. The results can be documented in the report tool and verified with the ¡°Configuration¡± tools plus the corresponding evaluation boards.

PROFET? +2 12V products provide a quick pick and place motherboard-daugtherboard approach. The motherboards serve as the basis for the evaluation kit, are compatible to all PROFET? +2 12V daughterboards and provide easy application adaptability with all devices of PROFET? +2 12V family.
The newly released PROFET? +2 12V products BTS70012-1ESP, BTS70015-1ESP & BTS70020-1ESP are equipped with the latest feature, called Capacitive Load Switching Mode
Why is it complicated to switch a capacitive load?
When switching on capacitors, high-inrush currents occur, which leads to the fact that temperature protection of the smart power controller in standard condition is triggered. Thereby the device latches off and the capacitor remains uncharged.
Why is a Capacitive Load Switching Mode beneficial?
By activating the Capacitive Load Switching Mode, big input capacitors can be charged and capacitive loads can be switched in the safe operating area. Moreover no discrete pre-charge circuitry is needed, no over-dimensioning of power switches occurs and supply stability is improved by reduction of current spikes during switch-ON.
How to activate and operate in Capacitive Load Switching Mode?
The Capacitive Load Switching Mode is an integrated product feature and can be activated by applying e.g. a 30kHz PMW signal to the IN pin. In this condition, slew rate is reduced, TJ (DYN) protection is set to a lower value and restart is activated. The capacitor gets charged by pumping and overtemperature protection remains untriggered.
With the success of the PROFET? +2 12V portfolio, a further step was taken to make use of the huge technology potential: to assess the performances of the PROFET? +2 12V family in a more accurate way, the current sense accuracy (kILIS) was tightened.
Benefits of the tighter kILIS accuracy:
- Fulfillment of OEM requirements e.g. Open Load in ON detection
- Enablement of a more precise device and load measurement
Thanks to the kILIS tightening the PROFET? +2 12V portfolio presents the best accuracy at low and nominal current range.
The two graphs on the right, show a comparison between the old and new kILIS tolerance of PROFET? +2 12V BTS7008-2EPA variant:
