The XP161A1256PRN is a voltage detector manufactured by Torex Semiconductor Ltd. This IC monitors voltage levels within a system and generates a reset signal if the voltage falls below a specified threshold. This crucial function prevents data corruption and ensures stable operation in sensitive electronic devices.

Applications:

• Microcontroller Reset: Provides a reliable reset signal for microcontrollers during power-up, power-down, or brownout conditions.
• Memory Protection: Prevents data corruption in memory devices by triggering a reset when the voltage drops below the minimum operating level.
• Battery Management Systems: Monitors battery voltage and initiates a shutdown sequence or low-battery warning to prevent deep discharge.
• Power Supply Monitoring: Detects undervoltage conditions in power supplies and triggers an alarm or shutdown.
• Industrial Control Systems: Enhances the reliability of industrial control equipment by monitoring critical voltage levels.

Features:

• High-Accuracy Voltage Detection: Features a precise voltage detection threshold with minimal variation.
• Low Current Consumption: Operates with very low supply current, making it suitable for battery-powered applications.
