MTCH652T-I/SS

Sensor And Detector Interfaces Overview

The MTCH652T-I/SS is a high-voltage line driver with an integrated boost converter, housed in a 28-pin SSOP package. It provides 19 high-voltage I/O lines and operates on a 1.8V to 5.5V input supply. The device features a built-in boost circuit driven by an external PWM signal, allowing selectable output voltages of 6V, 8V, 10V, 12V, 14V, 16V, or 18V. It supports a maximum SPI clock frequency of 1 MHz and includes configurable current limiting (up to 1A) and soft-start functionality to manage in-rush currents.

Sensor And Detector Interfaces Feature Summary

• Integrated voltage boost circuit with selectable output levels
• 19 high-voltage analog output channels
• Configurable current limiting and soft-start protection
• High-speed serial interface with independent output enable

Sensor And Detector Interfaces Applications

• Capacitive touch screen controller line drivers
• High-voltage display panel biasing
• Industrial control systems requiring isolated high-side switching

Sensor And Detector Interfaces Procurement Notes

Verify the ordering suffix 'I' corresponds to the industrial temperature range (-40°C to +85°C). Confirm the 'SS' suffix indicates the 28-pin SSOP package type. Ensure the 'T' suffix matches the required reel packaging quantity for automated assembly processes.

Sensor And Detector Interfaces Selection Notes

Select this component when 19 high-voltage outputs are required alongside an integrated boost solution. Compare against the MTCH650 if only 21 outputs are needed without internal boosting. Verify that the external PWM source can provide the necessary frequency and duty cycle for the boost regulator operation.

Sensor And Detector Interfaces Part Context

This part belongs to the MTCH650/2 family of programmable voltage boost devices from Microchip Technology. It shares the same pinout and serial interface protocol as the MTCH650 but differs by including an internal boost switch and inductor connection pin (LC).

Sensor And Detector Interfaces Replacement Considerations

The MTCH650-I/SS serves as a functional substitute if an external boost voltage source is already available in the design, as it lacks the internal boost circuitry.
