Overview

The MTCH9010-E/REB is a dedicated capacitive liquid level detection interface designed to operate in both capacitive and conductive modes. It provides a simple solution for sensing the presence of liquid through non-conductive barriers or directly with conductive probes, featuring a wide operating temperature range from -40C to 125C. The device outputs raw sensor data via UART and includes an adjustable threshold for easy integration into control systems.

Why Choose This Part

This sensor interface offers extremely low power consumption with a 1 uA sleep current and operates over a wide voltage range of 1.8V to 5.5V. It simplifies design by providing three different UART output formats and a heartbeat signal for system health monitoring, while supporting a variety of sensor electrode shapes and sizes.

Applications

Non-Contact Liquid Level Sensing
Detecting fluid levels through plastic or glass containers to prevent contamination or sensor corrosion.
Spill and Leak Detection
Monitoring for the presence of moisture or liquid on surfaces in industrial or appliance environments.
Condensation Monitoring
Identifying moisture buildup on cold surfaces in HVAC or environmental control systems.
Appliance Safety Switches
Implementing overflow protection or water presence checks in consumer appliances.

Getting Started

To begin development, interface the MTCH9010 via its UART pins to a microcontroller to view raw sensor values or configure the sleep period and detection thresholds. Designers can use the hardware configuration pins for quick setup or use the enhanced configuration mode via UART for fine-tuning sensor sensitivity and response times.
