MTCH102/5/8

2, 5 and 8-Channel Proximity/Touch Controller Data Sheet

Description

The Microchip mTouch

MTCH102/5/8 Proximity/Touch Controller with simple digital output provides an easy way to

add proximity or touch detection to any application. This device family implements capacitive sensors with active

guarding capability. The sensitivity and power mode can be configured through the MTSA and MTPM pins. The

MTCH102/5/8 devices also use an advanced optimization algorithm to actively suppress noise from the signal to

achieve reliable proximity/touch detection.

Features

• Capacitive Proximity and Touch Detection

System:

- High Signal to Noise Ratio (SNR)

- Adjustable sensitivity with compensation for

different sensor sizes

- Multi-stage active noise suppression filters

- Automatic environmental compensation

- Support wide range of sensor shapes and

sizes

• Simple I/O Interface with Existing System

• Smart Scan Scheduling

• Threshold Hysteresis

• Flexible Low-Power mode

• Brown-Out Protection

• Operating Voltage Range:

- 2.05V to 3.6V

• Operating Temperature:

- 40°C to +85°C

Typical Application

•

Light Switch

Portable Device Enabler

White Goods and Appliance

Office Equipment and Toys

Display and Keypad Back-lighting Activation

TO OUR VALUED CUSTOMERS

It is our intention to provide our valued customers with the best documentation possible to ensure successful use of your Microchip

products. To this end, we will continue to improve our publications to better suit your needs. Our publications will be refined and

enhanced as new volumes and updates are introduced.

If you have any questions or comments regarding this publication, please contact the Marketing Communications Department via

E-mail at

docerrors@microchip.com.

We welcome your feedback.

Most Current Data Sheet

To obtain the most up-to-date version of this data sheet, please register at our Worldwide Web site at:

http://www.microchip.com

You can determine the version of a data sheet by examining its literature number found on the bottom outside corner of any page.

The last character of the literature number is the version number, (e.g., DS30000000A is version A of document DS30000000).

Errata

An errata sheet, describing minor operational differences from the data sheet and recommended workarounds, may exist for current

devices. As device/documentation issues become known to us, we will publish an errata sheet. The errata will specify the revision

of silicon and revision of document to which it applies.

To determine if an errata sheet exists for a particular device, please check with one of the following:

• Microchip’s Worldwide Web site;

http://www.microchip.com

• Your local Microchip sales office (see last page)

When contacting a sales office, please specify which device, revision of silicon and data sheet (include literature number) you are

using.
