Descriptions:

The XC61CN1802NR is a low-power voltage detector designed to monitor power supply voltages in battery-operated and portable devices. It provides a reset signal when the supply voltage drops below the detection threshold (1.8V), ensuring system stability.

Features:

• Ultra-Low Power Consumption: Only 0.8µA typical current consumption.
• High Accuracy: ±1.5% detection voltage precision.
• Small Package: Compact SOT-25 package for space-constrained applications.
• Open-Drain Output: Allows flexible pull-up voltage selection.
• Built-in Hysteresis: Prevents chattering near the detection voltage.
• Wide Operating Range: Supports 0.7V to 6.0V input.

This IC is commonly used in microcontroller reset circuits, battery monitoring, and power management systems.
