MTCH102/5/8

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
