Dear Infineon support Team,

I want to replace BTS442 E2 by BTS441RG in one of our products and have following questions:

Most critical for us is the lower maximum allowed Vbb (abs.max) which is 63V for BTS442 and only 43V for BTS441. 

The datasheet of the BTS441RG recommends for overvoltage protections 150 Ohm between BTS441.GND and Signal GND.  I would like to implement these 150 Ohm but am wondering, if there are any further informations about this replacement:

1) do you have some further informations about replacing BTS442 E2 by BTS441RG not written in the datasheet?

2) Any drawbacks i might currently not be aware of using the 150 Ohm resistor for OV protection as proposed in datasheet?

3) is there a LTspice model for BTS441RG available? For example the BTS436L2G has one on your homepage.

Thank you very much in advance for your support!

Best regards,

Bastian

Hello. - Hi! May I ask

1. What exactly is the content of the green module UNDER_VOL_DET ECT ION on the left in Figure 33 of the Annex?

2. What is the specific function of the switching device Q4 in Figure 33 of the Annex?

3. Is there any more detailed information about the planar transformer in this picture? For example, design principle, number of turns, wire diameter, PCB, etc.
