SNIS211D October 2019 – November 2020 TMP63
PRODUCTION DATA
The TMP6 family feature a positive tempeature coefficient. During a short-to-supply condition, the thermistor will have increased current and power dissipated. Due to the positive temperature slope, the TMP6 will increase resistance and limit self-heating by design.
In contrast, a NTC would continually reduce resistance due to self-heating leading to a positive feedback of increasing power dissipation and decreasing resistance.
