Dear ALL

I wonder the Specific functional description of PROFET™ + 24V  Maximum supply voltage

for example ，the Maximum supply voltage of BTT6050-1ERA is 65V，

1.if my input voltage exceeds 65V, will it directly damage the switch？

2.if my input voltage less than 65V,but greater than maximum operating voltage（36V），will it be clamped to the normal opration voltage?

Is my understanding correct? Could you please help me clarify，many thanks~

Hello, I want to find the 24V low-side power switch, but only find the HITFET is optimized for 12V automotive applications, Can you offer some advice?  The best is 2 channels.

About ReverseON function of BTS7020,

If the load is LED, does ReverseOn work?
Does the output MOS of BTS7020 turn on? 

If you do not turn it on, please tell us why not.

Best regards,

Hi,

I want to know What is the voltage drop when the chip outputs 12A current

In fact, the result I tested was about 1.5V, and I want to compare it with the official data

Dear All

I'm testing TLE9104SH 

but no matter what data I send,I only can received 0x08B1.

could anybody kindly tell me where the problem is？

many thanks~

Hi all

I am trying to find a solution for replacing standard automotive relais with high side  switches. For some of them (12V) I will use the SPOC+2 BTS71040-4ESA to drive LEDs and some small consumers.

Since I also have 48V consumers (20A max), I will use  2ED4820-EM Gate Driver in combination with IAUC70N08S5N074 MOSFETs.

My question is, can I use this combination also for a 12V  battery switch relay? I've read that the minimum supply voltage is 20V. Or should I use the AUIR3241S instead?

Or even something else?

Thank you

Andy

How to find CMOS/BIPOLAR/BICMOS for an IC which is not given datasheet? For Example, IC  BTT62004ESAXUMA1 doesn't have the information of fabrication details. Kindly tell me the fabrication category of BTT62004ESAXUMA1 and also provide generalized technique to find for the ICs for which the details not available in datasheets.

Hello,

     TLE75602-ESH and TLE75620-EST have LED pack, But  the part number finishes with an “H” or “T” ,I want to know the difference between“H” and “T”.  Why  is there no  TLE75620-EST version  without  LED pack.

How to choose the package of Rsense resistor? Especially considering the fault condition where the fault current reaches 10mA.  Resistance package selection in the worst case.  Please provide the method and analysis for calculation.

Hi,

I am designing a high-side switcher using BT6163D as the below circuitry:

When A is 0V and VBB is 30V, why B and output is 27.1V? The behavior is correct or not?

But when A is 3.3V, output becomes 30V (equal to VBB)
