Functional Features

Voltage Monitoring

LP3470M5X-4.38 continuously monitors the supply voltage and generates a reset signal when the voltage drops below the preset threshold.

Manual Reset

The MR pin allows for manual reset functionality, enabling users to manually trigger a system reset.

Adjustable Timeout Period

The reset timeout period can be adjusted using external components, allowing customization based on specific application requirements.

Power-On Reset

LP3470M5X-4.38 provides a power-on reset signal to ensure proper initialization of the system during power-up.

Advantages and Disadvantages

Advantages

• Low power consumption helps conserve energy in battery-powered devices.
• Wide operating voltage range makes it compatible with various systems.
• High accuracy ensures reliable voltage monitoring.
• Small package size saves board space in compact designs.

Disadvantages

• The fixed reset threshold voltage may not be suitable for all applications.
• Limited number of pins restricts additional functionality without external circuitry.

Working Principles

LP3470M5X-4.38 operates by comparing the supply voltage with the preset threshold voltage. When the supply voltage drops below the threshold, the reset output is activated, triggering a system reset. The timeout period determines how long the reset signal remains active after the voltage returns to normal.
