Part Number: TMP411
My customer is using TMP411 and wants to know the THERM pin (pin 4) logic.
Test condition: -40 degree C, and TMP411 is used to enable the whole system. I want to double check the status of THERM pin at power on. is default setting for the THERM range 0~85C, or just below 85C?
customer found the system start up normally at -40C. could you please double confirm whether there's low temp limit at power up of the THERM pin?
Mike, The default startup THERM limit 0x55 (85C in standard temperature mode and 21°C in extended temperature mode, pg 25 of datasheet). Table 3 Register Map Summary also has the default value information for various registers. Is the customer experiencing problems? -Kelvin
In reply to Kelvin Le THS:
thanks for response. Customer's question is whether there's any low temperature limit for the THERM pin?
for ALERT or THERM2, there're both high and low limit. How about the THERM?
