The S-817A25ANB-CUD-T2 is a voltage detector IC manufactured by SII Semiconductor Corporation. This component is designed to monitor the voltage level of a power supply or battery and provide a reset signal when the voltage falls below a predefined threshold. This ensures stable operation of the connected system and prevents errors that may arise from insufficient voltage. This particular model has a detection voltage of 2.5V.

Applications

• Microcontroller and microprocessor systems: Provides a reliable reset signal during power-up and power-down sequences, preventing code execution errors.
• Battery management systems: Monitors battery voltage to prevent deep discharge, prolonging battery life and preventing damage.
• Power supply monitoring: Detects undervoltage conditions in power supplies, enabling protective measures to be taken.
• Industrial automation equipment: Ensures stable operation of control systems by monitoring critical voltage levels.
• Consumer electronics: Protects sensitive electronic components from damage caused by low voltage conditions.

Features

• High-precision detection voltage: Offers accurate voltage detection with a tolerance of approximately ±2%.
• Ultra-low current consumption: Minimizes power drain, making it suitable for battery-powered and energy-sensitive applications.
• Wide operating voltage range: Functions reliably across a range of input voltages.
• Compact package: Available in small surface-mount packages (e.g., SOT-23-5) for space-constrained designs.
• Hysteresis: Includes hysteresis to prevent output oscillation near the detection threshold.
• Built-in delay circuit: Provides a fixed or adjustable delay for the reset signal, allowing the system to stabilize before operation.
• Open-drain output: Allows flexible connection to various circuit configurations.

Benefits

• Improved system stability: Prevents malfunction due to voltage drops or fluctuations.
