BTS5215 polarity protection
This question is work. Just want to tell you so you don't feel bad about it. Very good answers may even be rewarded.
I wonder if somebody can help me or give me a hint about a "normal" design for automotive using Infineon BTSxxx IC's?
At the moment we use BTS5215, BTS711 (and also BTS660, BSP350, BSP762) and compared to the amount of failures we don't have a huge problem but still it's hard to get practical information from Infineon in application notes regarding a recommended design for normal automotive applications.
The failures we have had so far is "dead" Infineon IC's and in a few cases dead polarity protection (dead mosfet). If we exclude those "imaginative" connections (not a pure load and no power into the wrong places, our customers are relay people) we have a few failures we can't explain.
My question to you is: how would you have done regarding a "good" connection of Infineon products?
The polarity protection comes from Infineon but I can't find the document at the moment.
Despite the fact that a few BTS5215 aren't with us today, the IC is very neat, small size and capable of many amperes into any kind of load, lamps, motors, solenoids etc with no protection whatsoever if the load are within certain limits.
