Detailed Pin Configuration

MIC3808YMM features an 8-pin MSOP package with the following pin configuration:

1. GND (Ground)
2. VCC (Supply Voltage)
3. RESET (Active-Low Reset Output)
4. MR (Manual Reset Input)
5. TH (Threshold Voltage Selection)
6. CT (Reset Timeout Configuration)
7. NC (No Connection)
8. NC (No Connection)

Functional Features

• Voltage Monitoring: Monitors the supply voltage and provides a reset signal when it falls below a certain threshold.
• Adjustable Threshold: The threshold voltage can be adjusted to suit specific application requirements.
• Precision Monitoring: Provides accurate voltage monitoring with low hysteresis.
• Reset Timeout: Offers fixed or adjustable timeout periods for the reset signal.
• Manual Reset: Allows for manual reset of the device using the MR pin.

Advantages and Disadvantages

Advantages: - Low power consumption - Wide supply voltage range - Adjustable threshold voltage - Accurate and precise monitoring

Disadvantages: - Limited number of pins for additional functionality - Not suitable for high-voltage applications

Working Principles

MIC3808YMM operates by continuously monitoring the supply voltage. When the voltage falls below the set threshold, the reset output is activated, indicating a power failure or an out-of-range condition. The reset signal remains active until the voltage rises above the threshold or a timeout period elapses. The device can be manually reset using the MR pin.

Detailed Application Field Plans

MIC3808YMM finds applications in various fields, including:

1. Power Management Systems: Ensures proper operation of power supplies by monitoring voltage levels.
2. Battery-Powered Devices: Protects against undervoltage conditions, preventing damage to batteries and sensitive electronics.
3. Industrial Control Systems: Monitors critical voltages in industrial equipment to prevent malfunctions and ensure safety.
4. Automotive Electronics: Provides voltage supervision in automotive systems, enhancing reliability and performance.
