| Interface | 2 | Active | The MTCH108 is a 8 channels Proximity/Touch controller with 8 simple digital outputs. The sensitivity and power mode can be configured. The MTCH108 device uses an advanced optimization algorithm to actively suppress noise from the signal to achieve reliable proximity/touch detection. |
| Sensor and Detector Interfaces | 3 | Active | The Microchip MTCH112 Dual- Channel Proximity/Touch Controller provides an easy way to add proximity and/or touch sensor detection to any application. The device implements either two capacitive sensors or one sensor and one active guard driver, which is improving proximity performance. The optional device configuration through I2C™ allows presets to be loaded in a production environment. Automatic calibration routines are used by default to choose the best options, so user configuration
is not required. |
| Touch Screen Controllers | 2 | Active | The recommended alternative touch controller is [ATMXT144U](https://www.microchip.com/en-us/product/atmxt144u) or [ATMXT144U-A](https://www.microchip.com/en-us/product/atmxt144ud-a).
Microchip’s MTCH6102 is a turnkey projected capacitive touch controller that simplifies adding gestures to touch interface designs with industry-leading low power performance. Utilize up to 15 channels to support taps, swipes, and scrolling on XY touch pads and touch screens.
The MTCH6102 allows designers to quickly and easily integrate projected capacitive touch into their cost sensitive, low power application. The MTCH6102 provides developers with a flexible touch sensing solution to optimize common constraints of size, power and cost that are critical to applications such as wearable devices, remote controls, gaming devices and track pads. |

The [maXTouch](https://www.microchip.com/en-us/products/touch-and-gesture/maxtouch-touchscreen-controllers) portfolio covers solutions for all touch surfaces and touch screens up to 24" diagonal size. |
| Interface | 3 | Active | The MTCH650 is a line driver device, with 21 level shifters available. MTCH650 require only a 3-wire serial interface, latch enable (LE), and 2 capacitors.
While the MTCH650 and MTCH652 are very similar, the MTCH650 does not include a built-in boost circuit. The MTCH650 will require an external boost voltage device, such as the MCP16301. |
| Integrated Circuits (ICs) | 4 | Active | The MTCH652 is a compact boost convertor, with up to 19 level shifters, which provides an easy-to-use solution for driving High Voltage (HV) outputs.
MTCH652 requires only a 3-wire serial interface, latch enable (LE), 2 capacitors, a PWM, and a small inductor. The PWM is used to drive the boost and allows flexibility in duty cycle and frequency. The selectable internal Soft Start limits initial in-rush currents, preventing system brown outs. |

MTD6502B5v 3 phase sensorless brushless dc fan controller | Power Management (PMIC) | 3 | Obsolete | The MTD6502B is a 3-phase full-wave driver for brushless sensorless DC motors. They feature 180° sinusoidal drive, high torque output, and silent drive. Due to their adaptive features and wide power-supply range capabilities (2 to 5.5V) they are intended to cover a wide range of motor characteristics, while requiring no external tuning from the user. Speed control can be achieved through either power supply modulation or pulse-width-modulation (using the PWM digital input pin). Due to the compact packaging and minimum bill-of-material (power transistors incorporated, no Hall sensor, no external tuning), they are best suited for low-cost fan applications requiring high efficiency and low acoustic noise, such as CPU cooling fans. Frequency generator output is also included, enabling for precision speed control in closed-loop applications. The MTD6502B drivers include a lockup protection mode, which turns-off the output current when the motor is under lock condition, and an automatic recovery that enables the fan to run when the lock condition is removed. Motor over-current limitation, short-circuit protection, and thermal-shutdown protection are also included. |
