The MIC6315-30D3UY is a low-current voltage supervisor manufactured by Micrel (now part of Microchip Technology). It is designed to monitor voltage levels in electronic systems and provide a reset signal when the voltage drops below a specified threshold.

Applications

• Microprocessor-based systems
• Battery-powered devices
• Portable electronics
• Power supplies
• Real-time clocks (RTCs)

Features

• Precision voltage monitoring
• Fixed threshold voltage (3.0V)
• Low supply current
• Open-drain reset output
• Small package size

Benefits

• Prevents system malfunction due to low voltage conditions.
• Resets the microprocessor in a controlled manner.
• Extends battery life in portable devices due to low power consumption.
• Simplifies circuit design.
• Saves board space.

Additional Details

The MIC6315-30D3UY voltage supervisor monitors the input voltage and asserts a reset signal when the voltage falls below the 3.0V threshold. The reset output is an open-drain output, which requires a pull-up resistor. The low supply current makes it suitable for battery-powered applications. The small package size allows for use in space-constrained applications. The operating temperature range is typically -40°C to +85°C. It is typically used to monitor the supply voltage of a microprocessor or microcontroller and ensure that the system is reset properly during power-up or brown-out conditions.
