Pin 1: GND (Ground) Pin 2: MR (Manual Reset) Pin 3: VDD (Supply Voltage) Pin 4: RESET (Reset Output) Pin 5: NC (No Connection)

Functional Features

• Voltage Monitoring: The APX803S05-44SA-7 continuously monitors the supply voltage and provides a reset signal when it falls below the programmed threshold.
• Manual Reset: The MR pin allows for a manual reset, overriding the automatic reset functionality.
• Adjustable Threshold: The reset threshold voltage can be adjusted within a specified range to suit different application requirements.
• Reset Output: The RESET pin provides an active-low reset signal to the connected circuitry.

Advantages and Disadvantages

Advantages

• Low power consumption ensures minimal impact on overall system energy efficiency.
• High accuracy in voltage monitoring guarantees reliable operation.
• Wide operating voltage range makes it compatible with various electronic devices.
• Small package size enables space-saving integration into compact designs.
• Adjustable reset threshold voltage offers flexibility in different voltage level monitoring scenarios.

Disadvantages

• Limited number of pins may restrict its use in complex circuits requiring more I/O connections.
• Lack of built-in hysteresis feature may result in potential noise-induced false triggering.

Working Principles

The APX803S05-44SA-7 operates by comparing the supply voltage against the programmed threshold voltage. When the supply voltage drops below the threshold, the internal circuit triggers a reset signal, which remains active until the supply voltage rises above the threshold or a manual reset is initiated.

Detailed Application Field Plans

The APX803S05-44SA-7 finds applications in various fields, including but not limited to: 1. Power management systems 2. Battery-powered devices 3. Microcontrollers and microprocessors 4. Industrial automation 5. Automotive electronics 6. Consumer electronics
