The XC61CN1902NR-G is a voltage detector IC manufactured by Torex Semiconductor Ltd. It's designed to monitor the supply voltage of electronic circuits and provide a reset signal to microcontrollers or other critical components when the voltage drops below a pre-defined threshold. This ensures the system operates reliably and prevents data corruption or unpredictable behavior caused by undervoltage conditions.

Applications

• Microcontroller Reset Circuits: Provides a clean and reliable reset signal to microcontrollers during power-up or brown-out conditions.
• Power Supply Monitoring: Continuously monitors the power supply voltage and triggers an alert or shutdown if the voltage falls outside of acceptable limits.
• Battery Management Systems: Protects batteries from deep discharge by disabling the load when the battery voltage is too low, extending battery life.
• Embedded Systems: Used in a wide range of embedded systems to ensure reliable operation in the face of voltage fluctuations.
• Industrial Automation: Protects sensitive electronic equipment in industrial environments from power supply issues.

Features

• Low Power Consumption: Designed for minimal current draw to maximize battery life in portable applications.
• High Accuracy Voltage Detection: Provides precise voltage monitoring for reliable and predictable system behavior.
• Small Package Size: Available in compact surface-mount packages to save valuable board space.
• Wide Operating Voltage Range: Can operate across a broad range of supply voltages for versatile use.
