DEVICE OVERVIEW
The MTCH101 provides an easy way to add proximity
or touch detection to any human interface application.
The device integrates a single-channel capacitive
proximity detection, which can work through plastic,
glass or wood-front panel. It also supports a wide range
of conductive materials as sensor, like copper pad on
PCB, silver or carbon printing on plastic, Indium Tin
Oxide (ITO) pad, wire/cable, etc. On-board adjustable
sensitivity and Power mode selection allow the user to
configure the device at run time easily. An active-low
output will communicate the state of the sensor to a
host/master MCU, or drive an indication LED (see
Figure 1-1).

SENSITIVITY ADJUSTMENT
FIGURE 3-3:
The sensitivity of the system determines how far and
fast it can respond to proximity or touch. The MTCH101
provides the MTSA pin to adjust the sensitivity, and the
voltage on this pin will determine the sensitivity. VDD
voltage will give the lowest sensitivity, while GND
voltage will give the highest sensitivity.
The device will sample the voltage on the MTSA pin
after each scan, so it does not only support setting a
fixed sensitivity by a resistor ladder, but it also allows
adjusting the sensitivity dynamically, while the device is
running. A Digital-to-Analog Converter (DAC)
controlled by the host, or a hardware potentiometer can
be used to adjust the sensitivity. See typical circuit in
Figure 3-1 to Figure 3-4.

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.
FIGURE 4-1:
NORMAL MODE
Active Sleep: 69~105 ms
Scan
MTI
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.
FIGURE 4-2:
Active

LOW-POWER MODE
Sleep: 572~845 ms

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.

RESET
5.2
The MTCH101 can be stuck in a proximity-detected
state in some cases, such as sudden temperature
change, or higher dielectric materials (metal, wood or
glass) present near the sensor. Two methods can be
used to release the proximity-detected state without
repowering the device.
Reset by Touch and Release
A stuck release mechanism is implemented for this
device. When the device is stuck in a
proximity-detected state, the user can touch the sensor
pad and then release. This action will release the
proximity-detected state (see Figure 5-2).
FIGURE 5-2:
5.1
Reset by the MTPM pin
Changing the state of the MTPM pin, either from
low-to-high or from high-to-low, will reset the proximity
detection system and release the detection state. If the
device needs to keep the same Power mode, then a
pulse, which holds at least 4.5 ms, can be used to reset
the device (see Figure 5-1). This reset method can be
used at anytime during the operation, not only when the
state is stuck in a proximity-detected state.

INTERFACE WITH THE HOST
The MTO pin can be considered as an open drain
output. A pull-up resistor (usually 3.3k~10 k) is
needed to interface with a host. The pull-up voltage can
be any voltage lower than VDD. This allows a simple
interface with a lower VDD host device (see Figure 6-1).

Preliminary
 2012 Microchip Technology Inc.
Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
