MLX75026 QVGA Time-of-Flight Sensor
PRELIMINARY DATASHEET 3.4. Power Consumption The total power consumption is split over four domains, none of the four domains are consuming at the same time. VDDMIX and VDDIF are dominantly active during the integration time, VDD D and VDDA during the readout time and a small amount of VDDD is active constantly. As shown below in Figure 4. Figure 4: Power domains The following table lists the absolute peak current per domain, however the typical duty cycle of each active period is only around 10%.

Analog Supply Current IDDA 26.6 27.4 mA MIX Drivers Supply Current IDDMIX 544.1 1350.52 mA Digital Supply Current IDDD 91.7 120.0 mA I/O Supply Current IDDIF 2.1 2.6 mA Table 8: Peak current Note1 : Max. is the worst case peak current over the full ambient operating temperature range, over the full process variation and at worst case settings. Note2 : This value is the worst case peak current at -40˚C ambient temperature but realistically the system will not operate at this temperature so for PSU dimensioning we suggest to take into account the typical value. See Figure 6 for more information. Taking the according duty cycles into account will lead to the following average power consumption per domain.
