The I²C/SMBus output includes an open-drain ALERT pin for overtemperature interrupts — the output fan and alarm are on-chip, so no external comparator is needed.
The -40°C low end covers cold-boot and outdoor telecom environments.
Marked as Active on the lifecycle record with ROHS3 compliance. No last-time-buy or EOL notice is in effect.
The maximum accuracy is ±4°C over the full -40°C to 125°C temperature range and supply voltage range.
This part is sourced to order against an RFQ through independent distribution. Submit an RFQ for current availability and pricing.
The part is described as a DDR temperature sensor with I²C/SMBus output and an ALERT pin, which matches the DDR4 thermal monitoring specification (TSE2004av / TSE2002av). The ±4°C accuracy is within typical DDR4 requirements.
