Please select "Simulation Models (SPICE, S-parameters, SABER)"

If you cannot find your requested model there, please submit your request via the "click to request model" button on the right handed side.

Infineon uses only Spice and Saber models. These are a generally accepted standard that meets all simulation model requirements.

QUESTION: A prototype using the (BTS711L1 & BTS5210G) components was built, but in tests, BTS711L1 gives error reports. The current was 100mA. The BTS5210G was also used in the same application. This did not give any error feedback.
APPLICATION: Auto-heating system, Voltage- 24V, Current consumption per relay is 50mA. There are different channels, in some channels 2 relays used, some use 5 relays, etc.
After activation of the relay, the status output is checked. Some components immediately become LOW and the others will be LOW after a few minutes.
The 100-unit relay does not give an error signal. (No BTS5210G signal in the same circuit).
ANSWER: This means some relays (up to 5) are switched in parallel by one channel of the PROFET™s.
Refer to the "Over temperature of both channels" in truth table of the data sheet.
In the case of high signal at the inputs Inx and error message i.e., status pins STx go low and the outputs are going low. With the above, it could be diagnosed as an over temperature shut down.

Data Sheet BTS5210G.

We sold the optocoupler and solid state relay divisions to Vishay in 2001. Infrared Data Transceiver IRMxxx was affected as well.

The HVIC gate drive solution typically cuts down on component counts and PCB size by 50 percent compared to discrete solutions. These devices offer an improved immunity to voltage spikes and contribute to lower switching losses for the IGBTs and FETs. Fast switching times, under-voltage lockout protection, included deadtime are other advantages of these drivers.
Gate drive design compatibility of 600V and 1200V ICs reduces strongly the design time as the same basic circuit design and layout are re-used by just substituting the equivalent ICs.
