40 / 51 page ![]() DC and AC parameters STTS424E02 40/51 9 DC and AC parameters This section summarizes the operating measurement conditions, and the dc and ac characteristics of the device. The parameters in the dc and ac characteristics tables that follow, are derived from tests performed under the measurement conditions summarized in Table 26, Operating and AC measurement conditions. Designers should check that the operating conditions in their circuit match the operating conditions when relying on the quoted parameters. Table 26. Operating and AC measurement conditions Parameter Conditions Unit VDD supply voltage - temperature sensor 2.7 to 3.6 V Operating temperature -40 to 85 °C Input rise and fall times ≤ 5ns Input pulse voltages 0.2 to 0.8VDD V Input and output timing reference voltages 0.3 to 0.7VDD V Table 27. DC/AC characteristics - temperature sensor component with EEPROM Sym Description Test condition(1) Min Typ(2) Max Unit VDD Supply voltage 2.7 3.3 3.6 V IDD VDD supply current, active temperature conversions (no communication) EEPROM (inactive) SCL/SDA = VDD 100 210 µA VDD supply current, communication only (no conversions) EEPROM (not selected) 100 kHz 40 µA 400 kHz 115 µA IDD1 Shutdown mode supply current EEPROM, TS shutdown 2.0 mA EEPROM inactive, TS shutdown DA package at 85°C 1.0 3 µA DN package at 125°C 1.0 5 µA ISINK SMBUS output low sink current SDA forced to 0.6 V 6 mA IIH, IIL, IOH, IOL Input/output leakage current ±4 µA VPOR (3) Power on Reset (POR) threshold VDD falling edge: DA package 0.6 V VDD falling edge: DN package 2.0 V C-grade Accuracy for corresponding range 2.7 V ≤ VDD ≤ 3.6 V +75°C < TA < +95 ±1.0 ±2.0 °C +40°C < TA < +125 ±2.0 ±3.0 °C -40°C < TA < +125 ±3.0 ±4.0 °C |
