The CXHA3175 CXHA3176 is a temperature sensor, Delta-Sigma analog-to-digital converter, and digital over- temperature detector with SMBus interface. The host can query the CXHA3175 CXHA3176 at any time to read temperature. The open-drain Over temperature Shutdown (O.S.) output becomes active when the temperature exceeds a programmable limit. This pin can operate in either “Comparator” or “Interrupt” mode. The host can program both the temperature alarm threshold (TOS) and the temperature at which the alarm condition goes away (THYST). In addition, the host can read back the contents of the CXHA3175 CXHA3176's TOS and THYST registers. The sensor powers up in Comparator mode with default thresholds of 50°C TOS 45°C THYST. for CXHA3175 CXHA3176-1 and 80°C TOS , 75°C THYST for CXHA3175 CXHA3176-2.
