TMP431: alert when temp 'within' a range?

[FAE] Andrew Wang

Part Number: TMP431
Other Parts Discussed in Thread: TMP390, TMP303

Hi Team,

Customer is asking if TMP431 has the capability to alert user if temp is within a specific range? (Not beyond the limits)

So for example we make High Limit = 0C, Low Limit = 10C, would it work?

Thanks.

Hi Andrew,

Most temperature sensor IC operate as over-temperature alert with hysteresis. The low limit just sets the point at which the alert de-asserts on cool-down.

You probably want to look at window comparators like TMP390 and TMP303.

thanks,
