29 / 63 page  8.15.3 Temperature and Battery Monitor 8.15.3.1 Temperature Sensor Measured on a Texas Instruments reference design with Tc = 25 °C, VDDS = 3.0 V, unless otherwise noted. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT Resolution 2 °C Accuracy -40 °C to 0 °C ±4.0 °C Accuracy 0 °C to 105 °C ±2.5 °C Supply voltage coefficient(1) 3.9 °C/V (1) The temperature sensor is automatically compensated for VDDS variation when using the TI-provided driver. 8.15.3.2 Battery Monitor Measured on a Texas Instruments reference design with Tc = 25 °C, unless otherwise noted. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT Resolution 25 mV Range 1.8 3.8 V Integral nonlinearity (max) 23 mV Accuracy VDDS = 3.0 V 22.5 mV Offset error -32 mV Gain error -1 % 8.15.4 Comparator 8.15.4.1 Continuous Time Comparator Tc = 25°C, VDDS = 3.0 V, unless otherwise noted. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT Input voltage range(1) 0 VDDS V Offset Measured at VDDS / 2 ±5 mV Decision time Step from –10 mV to 10 mV 0.78 µs Current consumption Internal reference 9.2 µA (1) The input voltages can be generated externally and connected throughout I/Os or an internal reference voltage can be generated using the DAC 8.15.5 GPIO 8.15.5.1 GPIO DC Characteristics PARAMETER TEST CONDITIONS MIN TYP MAX UNIT TA = 25 °C, VDDS = 1.8 V GPIO VOH at 8 mA load IOCURR = 2, high-drive GPIOs only 1.56 V GPIO VOL at 8 mA load IOCURR = 2, high-drive GPIOs only 0.24 V GPIO VOH at 4 mA load IOCURR = 1 1.59 V GPIO VOL at 4 mA load IOCURR = 1 0.21 V GPIO pullup current Input mode, pullup enabled, Vpad = 0 V 73 µA GPIO pulldown current Input mode, pulldown enabled, Vpad = VDDS 19 µA GPIO low-to-high input transition, with hysteresis IH = 1, transition voltage for input read as 0 → 1 1.08 V GPIO high-to-low input transition, with hysteresis IH = 1, transition voltage for input read as 1 → 0 0.73 V GPIO input hysteresis IH = 1, difference between 0 → 1 and 1 → 0 points 0.35 V TA = 25 °C, VDDS = 3.0 V GPIO VOH at 8 mA load IOCURR = 2, high-drive GPIOs only 2.59 V GPIO VOL at 8 mA load IOCURR = 2, high-drive GPIOs only 0.42 V GPIO VOH at 4 mA load IOCURR = 1 2.63 V GPIO VOL at 4 mA load IOCURR = 1 0.40 V www.ti.com CC2651P3 SWRS257 – MARCH 2022 Copyright © 2022 Texas Instruments Incorporated Submit Document Feedback 29 Product Folder Links: CC2651P3 |
