Descriptions:

The XC61CN1902PR is a low-power voltage detector designed to monitor power supply voltages. It generates a reset signal when the supply voltage drops below the preset threshold (1.9V). The open-drain output makes it suitable for interfacing with various microcontrollers and logic circuits.

Features:

• Ultra-Low Power Consumption: Only 0.8μA typical current draw.
• High Accuracy: ±1.5% detection voltage precision.
• Wide Operating Voltage Range: Supports 0.7V to 6.0V.
• Built-in Hysteresis: Prevents unstable operation near the detection threshold.
• Compact Package: SOT-25 (5-pin) for space-constrained applications.
• Open-Drain Output: Allows flexible pull-up configuration.

This IC is commonly used in battery-powered devices, microcontrollers, and power management systems requiring reliable voltage monitoring.
