The MM3416Z10NRE is a voltage detector IC manufactured by Mitsumi Electric. This device is designed to monitor voltage levels within an electronic circuit and generate a reset signal when the voltage falls below a predefined threshold. This is crucial for preventing malfunctions, protecting data, and ensuring the stable operation of electronic systems.

Applications

• Microcontroller Systems: Provides a reliable reset signal to microcontrollers during power-up, power-down, and brownout conditions.
• Battery-Powered Devices: Monitors battery voltage to prevent deep discharge and extend battery life.
• Power Supply Monitoring: Detects undervoltage conditions in power supplies to trigger protective measures.
• Real-Time Clocks (RTC): Ensures accurate timekeeping by providing a reset signal to the RTC when the voltage is unstable.
• Memory Protection: Prevents data corruption in volatile memory during power failures or brownouts.

Features

• Precise Voltage Detection: Accurately monitors the input voltage and triggers a reset when the voltage drops below the threshold.
