The MM3511C26YRE is a voltage detector IC from Mitsumi Electric. Also known as a reset IC or power-on reset IC, it is designed to monitor the supply voltage and generate a reset signal when the voltage drops below a certain threshold. This ensures that the system starts up in a known state and prevents malfunctions due to undervoltage conditions.

Applications

• Microcontroller systems
• Microprocessor-based systems
• Power supply monitoring
• Battery-powered devices
• Embedded systems
• Reset circuitry
• System initialization

Features

• Detection Voltage: 2.6V (This is the voltage threshold at which the reset signal is asserted).
• Low Supply Current: Minimizes power consumption.
• Open Drain Output: Allows for flexible connection to various logic circuits.
• Small Package: Available in a compact package (e.g., SOT-25) for space-constrained applications.
• RoHS Compliant: Environmentally friendly construction.

Benefits

• System Stability: Ensures proper system initialization and prevents malfunctions due to undervoltage.
• Reliable Reset: Provides a reliable reset signal when the supply voltage is insufficient.
• Low Power Consumption: Minimizes power drain in battery-powered devices.
• Flexible Interface: Open drain output allows for easy integration with other circuits.

Technical Specifications

Detection Voltage (Vdet): 2.6V (typical)

Release Voltage (Vrel): A voltage slightly higher than the detection voltage, at which the reset signal is de-asserted.

Supply Voltage (Vcc): The maximum operating voltage (e.g., 5.5V)

Supply Current (Icc): Typically a few microamperes (μA)

Output Type: Open Drain

Operating Temperature Range: -40°C to +85°C

Package: SOT-25 or similar small surface-mount package.

The MM3511C26YRE voltage detector IC is a reliable and efficient solution for monitoring supply voltage and generating a reset signal in microcontroller and microprocessor-based systems.
