Hi,
I'm using TMP708 as temperature switch. The Rset is 20k which means that the temperature threshold is about 93 degree. But when the temperature reaches up to 80 degree, the OT pin will output low and trigger the system. When I add a 1uF capacitor paralleled with Rset. The temperature threshold becomes about 100 degree.
Please refer to the schematic as below.
My question is: 1. Why the difference is so big (93 degree to 80 degree)? 2. How about the influence when adding capacitor?
Thanks.
