The SGM800-1.63YN5G is a voltage detector manufactured by SG Micro Corp. It's designed to monitor a specific voltage level (1.63V in this case) and provide an output signal when the voltage falls below the threshold. This makes it suitable for applications like battery monitoring, power-on reset circuits, and over/under voltage protection.

Applications

• Battery Monitoring: Detecting low battery conditions in portable devices.
• Power-On Reset (POR): Generating a reset signal for microcontrollers and other digital circuits during power-up.
• Over/Under Voltage Protection: Protecting sensitive circuits from voltage fluctuations.
• System Monitoring: Monitoring power supply rails in various electronic systems.
• Brown-Out Detection: Detecting brown-out conditions and triggering appropriate actions.

Features

• Precision Voltage Detection: Accurately monitors voltage levels with a specific threshold.
• Low Quiescent Current: Minimizes power consumption in standby mode.
• Open-Drain Output: Allows for flexible voltage level translation and interfacing with different logic families.
• Small Package: Available in a small package (YN5G) for space-constrained applications.
• Fixed Threshold Voltage: Preset to detect voltage levels at 1.63V.
• Wide Operating Temperature Range: Typically -40°C to +85°C.

Benefits

• Reliable Voltage Monitoring: Provides accurate and reliable voltage detection.
• Extended Battery Life: Low quiescent current minimizes power drain in battery-powered applications.
• Flexible Interfacing: Open-drain output enables easy interfacing with various circuits.

Additional Details

The SGM800-1.63YN5G utilizes a precise internal reference voltage to achieve accurate voltage detection. The open-drain output requires a pull-up resistor to define the high-level output voltage. The value of the pull-up resistor should be chosen based on the supply voltage and the desired current consumption. The device is generally insensitive to minor voltage transients and offers good stability over temperature variations. The datasheet contains detailed electrical characteristics, timing diagrams, and application notes. It is supplied in tape and reel packaging for automated assembly. It is important to follow the manufacturer's recommended operating conditions for optimal performance and reliability.
