MTCH101
4.0 POWER MODE
The MTCH101 has two power mode options: Normal
mode and Low-Power mode. The state of the MTPM
pin determines the power mode.
4.1 Normal Mode Option
The device will run in Normal mode if the MTPM pin is
set high and no proximity or touch is detected. In this
mode, after an active scan, sleep time is between 69
and 105 ms, as shown in Figure 4-1. The sleep time
depends on the VDD voltage, the lower the voltage, the
more time it will be in the Idle state.

4.2 Low-Power Mode Option
The device will run in Low-Power mode if the MTPM pin
is set low and no proximity or touch is detected. In this
mode, after an active scan, sleep time is between 572
and 845 ms, as shown in Figure 4-2. As in Normal
mode, the sleep time depends on the VDD voltage, the
lower the voltage, the more time it will be in the Idle
state.

Note:
If the device makes a proximity or touch
detection, it will automatically perform
active scans continually. Once the device
releases from its proximity-detected state,
it will return to the power mode set by the
MTPM pin.
