PRODUCTION DATA.
In systems where there is a large amount of capacitance on the VDD node, the LM73-Q1 power supply ramp-up time can become excessively long. Slow power-supply ramp times may result in abnormal temperature readings. A linear power-on-ramp of less than 0.7 V/msec and an exponential ramp with an RC time constant of more than 1.25 msec is categorized as a slow power-supply ramp. To avoid errors, use the power up sequence described below.
The software reset sequence is as follows:
