Approach Detection

Figure 4-6. Approach Detection

Approach Detection is an embedded power-saving feature of Microchip’s Colibri Suite. It sends MGC3140

to Sleep mode and scans periodically the sensing area to detect the presence of a human hand. Utilizing

the built-in Self Wake-up mode, Approach Detection alternates between Sleep and Scan phase. During

the Scan phase, the approach of a human hand can be detected while very low power is consumed.

A detected approach of a user exceeding configured threshold criteria will alternate the MGC3140 from

Self Wake-up to Processing mode or even the application host in the overall system.

Within the Approach Detection sequence, the following scans are performed:
