Part Number: TMP390 Hi Team,
According to the Electrical Characteristics on page 5 of datasheet, Power Reset Time is 10 ms. During the 10 ms, what's status of OUTA pin?

Part Number: TMP390 The TMP390 has 2 modes of operation; dual channel or single channel for hot trip point.
The question is, when using it in one channel hot trip point; can the temperature range be the same as dual channel hot tip?

Hi Brian,
I recommend using TMP390 instead. It's two outputs are open-drain and intended to be tied together for the over/under operation you're looking for. LM57 does not offer under temperature alarm.
thanks,

Hi Sirs,
Sorry to bother you.
Could you help review schematic as below?
Any suggestion are welcome.
Schematic:
By the way, since our function is to detect close to the battery temperature, I intend to move him to the side.
Do you…
