The SQ52912 is a high-accuracy temperature sensor featuring a I2C/I3C-compliant digital interface.  Designed in line with the JEDEC JESD302-1 standard for Grade B devices, the SQ52912 surpasses the temperature accuracy requirements, making it a key component for optimizing DDR5 memory module performance. The SQ52912 is designed for low-power, high-accuracy thermal monitoring applications and is available in a compact 6-ball DSBGA package.

The SQ52912 operates with a core power supply of 1.8V and an I/O power supply of 1V. It features a low typical average quiescent current of 5.8μA during each 125ms conversion.

The SQ52912 offers a typical accuracy of ±0.3°C across the full temperature range of –40 °C to +125 °C. It integrates an on-chip 11-bit analog-to-digital converter (ADC) designed to operate with a 1.8V core power supply and a 1.0V I/O power supply. The SQ52912 also supports advanced features such as in-band interrupts, parity checks, and packet error checks.
