In one of the applications I use the BTS4140N,the output is loaded with 0.5A.
The supply voltage is 45V. the ambient temperature is 70°C.
After some time about 3-5min the limitation of the current starts. The output voltage also drops very sharply.
As soon as this behavior starts. The BTS4140N can no longer be switched off via pin 1 IN. But must be completely de-energized. Is this a normal behavior?
I have a second BTS4140N. This one is connected to the same supply voltage. But it is loaded and controlled separately. If one of the two BTS4140N starts with the behavior, so behaves also the other so. Is this also normal.
Thanks a lotShow Less
1:i had found in the datasheet of BTS7200-2PEA, don't find that the inrush current description, So i want to know how i can know the inrush current that could be support by this chip , And how long time of the inrush current
2: Another question, i saw that BTS7200-2PEA, for the datasheet, There max Inom=1.2A, So if i worked with 1.5A, How about the impact on the chipShow Less
I am designing an ECU for ADAS and there I am looking for a high-side switch with customizable over current threshold to protect my PCB, connector and passive filter network. Current is in the range of 2 to 4 A.
Can you help me to find a suitable Smart Power Switch?
Thx and BR, JohannShow Less
I require several thousand BTS432E2 - TO220 parts but cannot find any suppliers who have stock due to this being an end-of-life product.
Is there an alternative part number or a part that has superseding this component?
Any advice would be much appreciated.
The series resistor recommended for IN pin and status pin is 4.7K ohm for VDD of 5V. Could you provide a reference for the calculation so that the resistor can be tweaked as per the application.Show Less
I want to use more than 4 BTS7002 channels (10 exactly) in a power module distribution circuit for a race car.
Is it possible to use the hss-board-arduino.hpp shield library with more than 4 channels?
If yes how to modify it?
and if not would you have an example of code allowing to make the diagnosis without the library?
We have used Part No. BTS3011TEATMA1 in our TMLI_BMSH project.
The project is regarding the BMS for automotive applications.
Our query is to detect the fault/error conditions like
We want to understand the fault conditions for this part.
We have given voltage up to 60V, Current up to 15 Amp and temperature up to 150 deg. C, but in any of these conditions we are unable to detect any change in the status pin or cutoff of load current.
Hello, I want to switch 10A with BTS50085 using the circuit structure you see below. However, when we give the load over 5A and switch it to the mosfet, there is a voltage drop at the mosfet output. We tried this with both inductive and resistive load but got the same result. In this case, overheating occurs because too much power is consumed on the mosfet. We do not encounter any problems when we perform the mosfet switching first and then turn on the load. What are your solutions to this problem?
In the datasheet for ITS724G/BTS724G it says "replaces electromechanical relays, fuses and discrete circuits". I'm wondering what it practically means that it replaces fuses.
I'm using the device to drive lamps and solenoids. I have fuse on the incomming power cable but there is no fuse on the outputs after the ITS724G/BTS724G device.
I have seen that the device limits the current by turning output off and on when it gets overheated. It behaves as a pwm signal with the frequency of about 10-100 Hz. Frequency is high if "over current" is high.
Do you suggest having a PTC fuse or other resettable fuses on the output or can I relay on the built in protection in the ITS724G/BTS724G device? I do not have a uP that can read the diagnostic signal.
(In one of my other designs I have used the 428L2 device which have same protection features. This device did not hold for exessive over current. The device was driving a vibrator motor which consumed around 8 -13 A which is too much for the 428L2 device. I hade a 5A PPTC fuse (MC33165 ) on the output but that did not trip. Vibrator was only on for 5-20 seconds at the time)Show Less
Hello, we received a TLE75242-ESH loaner demo-board from our local rep but we are not able to find any documentation. Can documentation for the demoboard and daughter board be provided? Thank You...!Show Less
