The Conversion Ready Flag bit is set after all conversions, averaging, and multiplication operations are complete. The Conversion Ready Flag bit clears under these conditions: 1. Writing to the Configuration Register, except when configuring the MODE bits for power-down mode; or 2. Reading the Status Register. Power Calculation The Current and Power are calculated following shunt voltage and bus voltage measurements as shown in Figure 20. Current is calculated following a shunt voltage measurement based on the value set in the Calibration Register. If there is no value loaded into the Calibration Register, the current value stored is zero. Power is calculated following the bus voltage measurement based on the previous current calculation and bus voltage measurement. If there is no value loaded in the Calibration Register, the power value stored is also zero. Again, these calculations are performed in the background and do not add to the overall conversion time. These current and power values are considered intermediate results (unless the averaging is set to 1) and are stored in an internal accumulation register, not the corresponding output registers. Following every measured sample, the newly-calculated values for current and power are appended to this accumulation register until all of the samples have been measured and averaged based on the number of averages set in the Configuration Register. Figure 20. Power Calculation Scheme In addition to the current and power accumulating after every sample, the shunt and bus voltage measurements are also collected. Once all of the samples have been measured and the corresponding current and power calculations have been made, the accumulated average for each of these parameters is then loaded to the corresponding output registers, where they can then be read. 10 Submit Documentation Feedback Copyright © 2011, Texas Instruments Incorporated Product Folder Link(s): INA226 |
