The S-80851CNMC-B9C-T2 is a voltage detector IC manufactured by SII Semiconductor Corporation. This IC monitors the input voltage and generates a reset signal when the voltage drops below a defined threshold. This is vital to protect microcontrollers and other sensitive electronic components from damage or malfunctioning due to undervoltage conditions.

Applications

• Microcontroller reset circuits
• Power management systems
• Battery-powered devices
• Industrial control equipment
• Consumer electronics

Features

• Detection voltage: 5.1V (Nominal)
• High-accuracy detection voltage
• Low current consumption
• Package: SOT-23-5
• Built-in hysteresis
• Output: N-channel open drain

Benefits

• Prevents errors in microcontroller systems caused by low voltage.
• Extends battery life in portable devices due to low power consumption.
• Provides a stable reset signal, avoiding oscillations because of the built-in hysteresis.
• Offers circuit design flexibility with the N-channel open drain output.
• Saves board space because of the small SOT-23-5 package.

The S-80851CNMC-B9C-T2 provides accurate voltage detection and consumes very little power. The integrated hysteresis prevents unwanted reset signals. Its open-drain output allows for versatile integration with other circuits. The SOT-23-5 package makes it suitable for applications where space is limited. This voltage detector provides a reliable and efficient way to protect electronic systems from undervoltage problems.
