Other Parts Discussed in Thread: TMP390, TMP392
Hi TI:
I jump wire to connect TMP709.
Ther Rset is 68K ohm.
So the temperature is set to about 31 degree celsius.
The hyst pin is set to GND.
I use a hair dryer to heat the air temperature.
I think the air temperature will above 31 degree celsius.
The hair dryer is very hot.
But the OTpin did not sink low?
I use pull high 10K ohm for OT pin.
I wonder 10K ohm is not high enough.
So I change 10K ohm to 500K ohm.
But OT pin did not sink low?
I really do not know why OT pin did work?
Can TMP709 detect the air temperature or there is something wrong?
best regards
