(1) Typical measurements performed at 25°C and nominal voltage
(2) Measurements taken at –40°C, 25°C, and 105°C. 3.3V inputs measured at 3V, 3.3V, and 3.6V. 6V inputs measured at 5.5V, 6V, and 7V. The maximum current draw of all these conditions is shown.
(3) This number represents the current at the input to the TPS99001-Q1 when the DMD voltage rails output the maximum current as listed in the respective sections of this data sheet. This number is the combination of the measured current when the DMD voltage regulator is unloaded (3mA typical, 56mA max) and the estimated current draw on the 6V supply when the DMD voltage regulator outputs the maximum current (63mA). The estimated current draw is calculated by the equation I6V = [(16 / 6) × IVBIAS + (8.5 / 6) × IVOFFSET + (–10 / 6) × IVRESET] / η where η = 0.9. In order to calculate the power dissipation of the TPS99001-Q1 in this condition, multiply the current from the unloaded condition by the input voltage and add the current from the DMD voltage regulator multiplied by the input voltage multiplied by (1 – η).
