The S-80135CNMC-JKUT2G is a CMOS voltage detector IC manufactured by ABLIC U.S.A. Inc. It's designed to monitor voltage levels and issue a reset signal when the voltage drops below a pre-defined threshold. The key features are its low current consumption, high detection accuracy, and small form factor, making it well-suited for battery-powered and portable electronic devices.

Applications

• Microcontroller Reset: Resets a microcontroller when the power supply voltage falls below the required level.
• Battery Voltage Monitoring: Monitors the battery voltage in portable devices and triggers an action when it's low (e.g., turn off the device).
• Power Supply Monitoring: Detects undervoltage conditions in power supplies and shuts down the system to prevent damage.
• Data Protection: Protects data in memory devices by preventing write operations during low-voltage conditions.
• System Monitoring: General-purpose voltage monitoring in various electronic systems.

Features

• Detection Voltage: 3.5V (Based on the part number S-80135CNMC-JKUT2G).
• Ultra-Low Current Consumption: Minimizes the load on the power source, prolonging battery life in portable applications.
• High Detection Accuracy: Provides a reliable and accurate voltage detection threshold.
• Small Package: Typically available in compact packages like SOT-23, enabling use in space-constrained applications.
