The XC61CC1502NR is a voltage detector from Torex Semiconductor, designed to monitor voltage levels and provide a reset signal when the voltage drops below a predefined threshold. This functionality is critical for protecting microcontrollers and other voltage-sensitive components from damage or malfunction due to undervoltage conditions.

Applications

• Microcontroller Reset Circuits: Provides a reliable reset signal during power-up or brown-out conditions.
• Power Supply Monitoring: Detects voltage drops and initiates shutdown or alarm procedures.
• Battery-Powered Devices: Monitors battery voltage and prevents deep discharge.
• Embedded Systems: Ensures stable operation by monitoring the supply voltage.
• Industrial Control Equipment: Provides voltage supervision in harsh industrial environments.

Features

• High-Accuracy Voltage Detection: Precisely monitors the input voltage.
• Low Current Consumption: Minimizes power drain, extending battery life.
• Small Package: Enables integration into space-constrained applications.
• Open Drain Output: Provides flexible interfacing options.
• Hysteresis: Prevents oscillations and ensures stable operation.

Benefits

• Improved System Reliability: Prevents data corruption and system crashes.
• Extended Battery Life: Reduces the load on the power source.
• Simplified Circuit Design: Minimizes the need for external components.
• Protection Against Undervoltage: Safeguards sensitive components from damage.
• Stable Operation: Prevents false resets caused by voltage noise.

The XC61CC1502NR features a detection voltage of 1.5V. It comes with an open drain output, requiring an external pull-up resistor. Its low power consumption makes it ideal for battery-powered applications. The hysteresis feature helps to prevent unwanted resets due to voltage fluctuations. The package is typically a small SOT-25 or similar.

This voltage detector ensures reliable system operation by monitoring the supply voltage and triggering a reset when the voltage falls below the set threshold. Its integrated hysteresis further enhances stability by preventing oscillations around the threshold voltage.
