The XC61CN2802PRN is a voltage detector IC manufactured by Torex Semiconductor Ltd. It is designed to monitor voltage levels and assert a reset signal when the voltage drops below a specified threshold. This function is vital for maintaining the stability and preventing malfunctions in electronic systems that are sensitive to voltage fluctuations.

Applications

• Microcontroller Supervision: Provides reset functionality to microcontrollers during power-up, power-down, or brown-out conditions.
• Power Supply Monitoring: Monitors the output voltage of power supplies, providing an alert or initiating a shutdown if the voltage falls out of regulation.
• Battery-Powered Devices: Protects battery-powered devices from deep discharge by shutting down the system before the battery voltage reaches a critical level.
• Memory Protection: Prevents data corruption in volatile memory by asserting a reset during undervoltage conditions.
• Industrial Control Systems: Enhances the reliability of industrial equipment by monitoring voltage levels and responding to voltage drops.

Features

• Precise Voltage Detection: Accurately monitors the input voltage and triggers the reset signal at the specified threshold.
• Low Quiescent Current: Minimizes power consumption, extending battery life in portable applications.
• Small Package Size: Available in compact packages such as SOT-23, saving valuable board space.
• Built-in Hysteresis: Prevents oscillations near the threshold voltage, ensuring stable and reliable operation.
• Open Drain Output: Offers flexibility in interfacing with different logic levels.

Benefits

• Increased System Reliability: Prevents system crashes and data corruption caused by voltage fluctuations.
