Functional Features

• Monitors supply voltage and asserts reset output when voltage falls below the threshold.
• Provides a manual reset input for immediate system reset.
• Offers multiple threshold voltage options for flexibility in different applications.

Advantages and Disadvantages

Advantages: - Low-power consumption - Precision monitoring of voltage levels - Small package size - Wide operating temperature range

Disadvantages: - Limited threshold voltage options - No adjustable timeout period

Working Principles

MIC3809YM operates by continuously monitoring the supply voltage using an internal voltage reference and comparator. When the voltage falls below the selected threshold, the reset output is asserted. The reset remains active until the voltage rises above the threshold or a manual reset signal is received.

Detailed Application Field Plans

MIC3809YM finds applications in various fields, including:

1. Battery-Powered Devices: Ensures proper operation and prevents damage due to low voltage conditions.
2. Microcontrollers and Processors: Provides a reliable reset signal during power-up or voltage fluctuations.
3. Industrial Control Systems: Monitors power supply integrity and initiates system reset if necessary.
4. Automotive Electronics: Protects sensitive components from voltage drops and ensures safe operation.

Detailed and Complete Alternative Models

Some alternative models that offer similar functionality to MIC3809YM are:

1. MAX809: Low-power voltage supervisor with adjustable threshold and timeout period.
2. LTC2910: Precision voltage monitor with programmable threshold and adjustable reset timeout.
3. TPS3839: Ultra-low quiescent current voltage supervisor with fixed threshold options.
