PRODUCTION DATA.
In some severe conditions, such as the ISO7637-2 test or the loss of battery with inductive loads, a negative pulse occurs on the GND pin This pulse can cause damage on the connected microcontroller. TI recommends serial resistors to protect the microcontroller, for example, 4.7-kΩ when using a 3.3-V microcontroller and 10-kΩ for a 5-V microcontroller.
