MTCH102 Datasheet, PDF (7/37 Pages) Microchip Technology – 2, 5 and 8-Channel Proximity/Touch Controller Data Sheet

GC
The GC (Guard Control) is multiplexed with one of the
MTOx pins. By grounding the GC pin, the active guard
signal will be enabled on the Guard pin.
MTSA
The MTSA pin is an input that determines the
sensitivity of touch/proximity sensors. Applying VDD will
give the lowest sensitivity while applying VSS will give
the highest.
MTPM
The MTPM pin is an input that determines the power
mode of MTCH10X devices. By connecting VSS to the
MTPM pin, the device will operate in Low-Power mode.
See Figure 5-1 for current consumption and response
time specifications. When applying VDD on the
MTCH10X MTPM pin, the device will scan the sensors
at the fastest possible sampling rate. Host-controlled
sampling rates are available using the Smart Scan
Scheduling feature described in Section 4.0, Power
Mode and Timeout Reset.
