The XC61AC2802MR is a voltage detector IC manufactured by Torex Semiconductor Ltd. Voltage detectors, also known as voltage supervisors or reset ICs, are designed to monitor the supply voltage of electronic circuits and generate a reset signal when the voltage falls below a pre-defined threshold. This ensures that the system starts up correctly and avoids unpredictable behavior due to low voltage conditions.

Applications

• Microcontroller reset circuits
• Power supply monitoring
• Battery-powered devices
• System initialization
• Watchdog timers

Features

• Accurate voltage detection
• Low power consumption
• Small package size
• Adjustable detection voltage (potentially through external components, verify datasheet)
• CMOS output

Benefits

• Improved system reliability by preventing operation at low voltage
• Reduced power consumption, extending battery life in portable devices
• Simplified circuit design with integrated voltage detection
• Compact size for space-constrained applications

Additional Details

The XC61AC2802MR features a precise voltage detection threshold, ensuring accurate voltage monitoring. Its low power consumption is crucial for battery-powered devices. The CMOS output is compatible with a wide range of logic circuits. The MR at the end of the part number likely refers to the package type (e.g., SOT-23, USP). Some voltage detectors offer adjustable detection voltages through the use of external resistors, allowing for customization to specific application requirements. Consult the manufacturer's datasheet for detailed specifications, including detection voltage, release voltage, operating temperature range, and package information. Also check if the reset is active high or active low.
