MTCH652T-I/MV

Sensor And Detector Interfaces Overview

The MTCH652T-I/MV is a compact boost converter with 19 high-voltage level shifters, designed to drive capacitive touch line drivers. It operates on an input voltage range of 1.8V to 5.5V and features a built-in boost circuit driven by an external PWM signal. The device provides selectable output voltages from 6V to 18V and includes configurable current limiting up to 1A. It utilizes a high-speed SPI interface for configuration and offers low quiescent current (<200 µA) and shutdown current (1.5 µA typical). The component is housed in a 28-pin UQFN package.

Sensor And Detector Interfaces Feature Summary

• Integrated voltage boost circuit with selectable output levels
• Configurable current limiting and soft-start functionality
• Independent Output Enable control separate from serial interface

Sensor And Detector Interfaces Applications

• Capacitive touch screen controller systems
• High-voltage line driver applications
• Industrial touch sensing interfaces

Sensor And Detector Interfaces Procurement Notes

Verify the specific ordering suffix MV corresponds to the UQFN-28 package and industrial temperature grade. Confirm that the required external components, including the PWM source and inductor, are sourced separately as they are not included with the IC. Ensure the design accounts for the minimum order quantities if purchasing from distributors.

Sensor And Detector Interfaces Selection Notes

Select this model over the MTCH650 when an integrated boost solution is required, as the MTCH650 lacks internal boosting capabilities. Consider the 19-channel count versus the MTCH650's 21 channels based on system requirements. Verify that the host microcontroller can provide the necessary PWM signal for the OSCIN pin to drive the internal switch.

Sensor And Detector Interfaces Part Context

This component belongs to the MTCH650/2 series of programmable voltage boost devices with built-in level shifters. It shares the same package footprint and serial interface protocol as the MTCH650 but differs internally by including the boost switching transistor and diode. This integration simplifies the bill of materials for high-voltage generation compared to the external boost requirement of the MTCH650.

Sensor And Detector Interfaces Replacement Considerations

The MTCH650T-I/MV is a related part within the same family but lacks the built-in boost circuit. Direct substitution requires verifying if the application already has an external boost supply or if one must be added. No other direct cross-manufacturer equivalents are documented in the official datasheet.
