Part Number: LM57 Other Parts Discussed in Thread: TMP390 Tool/software: Please could you provide an example circuit using two LM57 sensors that would provide a single on / off control line to a DC/DC converter.
The DC/DC should power off above +85…
Part Number: LM57 Hi all
My customer is looking for the package drawing / package dimensions for the LM57BISD-5/NOPB (package WSON – NGR 8)
This is not in the datasheet and also no dimensions for the document found at https://www.ti.com/support-packaging…
Part Number: LM57-Q1 Hi All,
For this part LM57TSPWQ1,
Without RSENSE1 & RSENSE2 resistor, Can we take analog (Vtemp) output. what will the default gain?
Moreover Please confirm IC still give the Vtemp output or which gain??
Part Number: LM57 If I want to measure ambient more accurately, should I remove the ground or any plane under LM57 to limit the heat picking up from the board?
Part Number: LM57 We’re looking into using the LM57 as a temp sensor to switch off a load when the chip temp rises above -37C. We want to guarantee that the load is switched on from -55C to -37C.
Our low level functional temp range is -55C; this is…
The first post has some problems. So i am posting it again.
We are planning to use LM57 in one our application.
The application works from -55 deg C. LM57 will act as thermostatic switch in our application.
Tover threshold = -35 degC.

Part Number: LM57-Q1 Other Parts Discussed in Thread: LM57 Hi Team
If LM57 Rsense1 or Rsense2 short to GND. What temperature will be show or What will happened
Part Number: LM57 I'm looking at using LM57 to turn on heater at 10C, and turn off at 15C.
I figured that I need to pick 5C hysteresis part. However since I only have one trip point, should I tie SENSE2 to ground or leave it floating?
Hi Sugiyama-san,
As far as I know, LM57 released two type of hysteresis 5°C and 10°C for automotive. Based on your description, it looks like customer had the 5°C hysteresis. Could you please provide me more information on customer's application via…
