The S-80841CLUA-B62-T2 is a voltage detector IC manufactured by SII Semiconductor Corporation. It is designed to monitor the supply voltage and generate a reset signal when the voltage drops below a certain threshold, ensuring stable operation of electronic devices.

Applications

• Microcontroller Reset Circuits: Provides a reliable reset signal to microcontrollers during power-up or brown-out conditions.
• CPU Reset Circuits: Ensures that CPUs start in a defined state after power is applied or after a voltage drop.
• Power Supply Monitoring: Monitors the output voltage of power supplies and triggers an alarm or shutdown if the voltage is outside the specified range.
• Battery-Powered Devices: Protects battery-powered devices by shutting down when the battery voltage is too low, preventing deep discharge.
• Industrial Control Systems: Monitors voltage levels in industrial equipment to prevent damage from voltage fluctuations.

Features

• Low Voltage Detection: Detects when the input voltage falls below a predetermined threshold (likely 4.1V based on the '41' in the part number).
• High-Precision Detection Voltage: Provides accurate voltage detection for reliable monitoring.
• Low Current Consumption: Minimizes power consumption, making it suitable for battery-powered applications.
• Built-in Hysteresis: Prevents false triggering due to noise or voltage fluctuations.
• Open-Drain Output: Allows for flexible connection to various logic circuits.

Benefits

• Improved System Reliability: Ensures stable operation by resetting the system during voltage drops, preventing data corruption and malfunctions.
• Data Protection: Protects data by initiating a safe shutdown during power failures.
• Extended Battery Life: Low current consumption maximizes battery life in portable devices.
• Simplified Design: Integrates the voltage detection function into a single chip, simplifying circuit design.
• Cost-Effective Solution: Provides a cost-effective solution for voltage monitoring and reset generation.

Additional Details

The S-80841 series voltage detectors are available in various package options. The detection voltage is fixed and determined by the part number (4.1V based on '41'). The output is typically an open-drain NMOS transistor, requiring an external pull-up resistor. The B62 likely refers to a specific product specification or manufacturing code. The 'T2' indicates tape and reel packaging.
