The XC61CN4602MR is a voltage detector IC manufactured by Torex Semiconductor Ltd. It is designed to monitor a voltage supply and issue a reset signal to a microcontroller or other digital system when the voltage falls below a predefined threshold. This prevents the system from operating with an insufficient voltage supply, which can lead to unpredictable behavior or data corruption. The device is known for its high accuracy and low current consumption, making it suitable for battery-powered and other power-sensitive applications.

Applications

• Microcontroller reset circuits
• Battery voltage monitoring
• Power management in portable devices
• Overvoltage and undervoltage protection
• Real-time clock (RTC) backup systems

Features

• High detection voltage accuracy: ±2%
• Ultra-low power consumption
• Operating voltage range: 1.6V to 6.0V
• Built-in hysteresis to prevent oscillations
• Small SOT-25 package for space-saving design
• Open drain output type

Benefits

• Ensures system stability by preventing operation at low voltage levels.
• Extends battery life in portable applications due to its low current draw.
• Simplified circuit design with integrated hysteresis.
• Compact size ideal for high-density circuit boards.
• Provides a clean and reliable reset signal to connected devices.

The XC61CN4602MR has a detection voltage of 4.6V. The open drain output enables flexible connection to various logic levels and microcontrollers. The hysteresis feature prevents the device from rapidly switching on and off when the input voltage is close to the detection threshold, thus avoiding false reset signals. This is critical for maintaining system reliability. The SOT-25 package makes it a good choice for applications where board space is at a premium. The device's high accuracy ensures that the system is reset only when absolutely necessary, minimizing unnecessary interruptions.
