For positive temperatures (for example, +50
°C):
Twos complement is not performed on positive numbers. Therefore, simply convert the number to binary code
with the 13-bit, left-justified format, and MSB = 0 to denote a positive sign.
Example: (+50
°C)/(0.0625°C/count) = 800 = 320h = 0011 0010 0000
For negative temperatures (for example,
–25°C):
Generate the twos complement of a negative number by complementing the absolute value binary number and
adding 1. Denote a negative number with MSB = 1.
Example: (
–25°C)/(0.0625°C/count) = 400 = 190h = 0001 1001 0000
Twos complement format: 1110 0110 1111 + 1 = 1110 0111 0000
PVLD
Power Valid Flag
Bit 1
This bit is the power valid flag.
The TMP512/13 do not start a temperature conversion if the power supply is not valid. If the voltage is less than
2.7V during a conversion, the PVLD bit is set to '1' and the temperature result may be incorrect.
