Part Number: TMP390 Tool/software: Hi ti team，
The current problem is that the temperature fluctuates from 0 to 5 degrees, and the temperature lag function is lost. Please confirm if it is normal?
The chip was tested in a high and low temperature chamber…
Part Number: TMP390 Tool/software: Hi,
The TMP390 has two outputs (OUTA and OUTB). The data sheet specifies them as open-drain active low outputs, but there are no resistance values specified for the open state. Is it possible to connect both outputs…
Part Number: TMP390-Q1 Tool/software: Hello,
I'm using the TMP390AQDRLRQ1 IC for over-temperature protection in my design. I want a hysteresis of 20°C, so I have grounded the SETB pin and pulled down the SETA pin using a 39K (RK73H1ETTP3902F) resistor…
Part Number: TMP390 Tool/software: I have constructed the below circuit to provide temperature lockout/protection to our device. The goal is to disable a buck converter when temperature is outside the range [-40C - 120C]. The CH. A/B outputs are tied…
Part Number: TMP390-Q1 Other Parts Discussed in Thread: TMP390 I am looking for information on where the TMP390 sensors are being built. Are these in the US or outside of the US?
Thanks,

Hi TI experts，
I want to know what is the internal block diagram of the TMP390 temperature switch? Can you provide it? Because when I was designing the circuit diagram, I was worried that after the temperature protection was…
Part Number: TMP390 I require a 0C temperature switch with very low standby power consumption. I have built the single channel cold trip-point circuit from the datasheet (Fig 8-7) with RSET as 21.5k for a 0deg threshold and 5deg hysteresis. When measuring…
Part Number: TMP390 Hello Expert, I have question regarding TMP390's config resister. In datasheet, it showed parameter setting on a lot of resisters. However, our customer cannot use such a high accuracy resister. Then, I'd like to get the formula that…
Part Number: TMP390 Hi Team,
My customer study the TMP390 datasheet and found below chart. He thought the trip error is covered over the detection temp. range, so he would like set Hot Trip temperature below 30C. For example, set cold trip temp. to -20C…
Part Number: TMP390 Hi,
My customer want find temperature switch about below behavior.
1. When T=-30C, enable heater.
2. When T= 25C, disable heater.
3. When T= 15C, enable heater.
4. When T= 25C, disable heater. (repeat step3,4 until system shutdwon…
