Equation 1
The purpose of factor n is to determine the number of external temperature sense diodes (in
series). With factor m the level of the threshold voltage can be fine tuned.
Read device information (ROM)
The device information is stored at the ROM addresses defined below and is read using the
respective operating code.
Table 43.
The <ID-Header> indicates the product family and specifies how many bytes of device
information are available.
