Descriptions:

The XC61CC3902MR is a low-power voltage detector designed to monitor power supply voltages and generate a reset signal when the voltage falls below a preset threshold (3.9V). It features an ultra-low quiescent current, making it suitable for battery-powered applications.

Features:

• Low Power Consumption: 0.7μA typical current
• High Accuracy: ±1.5% detection voltage precision
• Built-in Hysteresis: Prevents chattering near the detection threshold
• Open-Drain Output: Allows flexible interfacing with other circuits
• Wide Operating Voltage Range: 1.0V to 6.0V
• Small Package: SOT-25 for space-constrained designs

This IC is commonly used in power management circuits, microcontrollers, and portable electronics to ensure stable operation by monitoring supply voltage levels.
