MGC3X30 Power Profile

The MGC3X30 power profile is illustrated in Figure 4-5.

FIGURE 4-5:

MGC3X30 POWER PROFILE

MGC3X30 current consumption for the different

operation modes are summarized in Table 4-1.

The Self Wake-up mode current consumption depends

on the number of active channels during Self Wake-up

mode, Approach Scan and Calibration Scan repetition

period. Changing these parameters results in different

current consumption values.

Wake-up IRQ from host

or I²C

TM start detected

Approach detected

No user interaction

Processing

IPEAK: Processing mode with 5 Rx Channels

ISW1: Self Wake-up with 150 ms Approach Scan and 10s Calibration Scan

ISW2: Self Wake-up with 150 ms Approach Scan and without Calibration Scan

IDS:

VDD = 3.3V

5 Rx Channels activated

Self Wake-up mode

110 µA

VDD = 3.3V

No Calibration Scan

1 Rx Channel active

200 µA

1 Rx Channel active

Deep Sleep mode

9 µA

VDD = 3.3V

Note:

In Processing mode, there are always five

Rx channels activated. Choosing only four

Rx channels in Aurea does not have an

impact on the current consumption during

Processing mode.
