PRODUCTION DATA
Refer to the PDF data sheet for device specific package drawings
In many conditions, such as the negative surge pulse, or the loss of battery with an inductive load, a negative potential on the device GND pin may damage the MCU I/O pins [more likely, the internal circuitry connected to the pins]. Therefore, the serial resistors between MCU and HSS are required.
Also, for proper protection against loss of GND, TI recommends 10 kΩ resistance for the RPROT resistors.
