Pin 1: GND (Ground) Pin 2: MR (Manual Reset Input) Pin 3: VCC (Supply Voltage) Pin 4: RESET (Reset Output) Pin 5: TH (Threshold Voltage Selection)

Functional Features

• Monitors the voltage level of a power supply.
• Provides a reset signal when the voltage drops below the selected threshold.
• Manual reset input allows for external reset control.
• Low quiescent current ensures minimal power consumption.

Advantages

• Wide supply voltage range allows for versatile applications.
• Multiple threshold voltage options provide flexibility in voltage monitoring.
• Small package size (SOT23-5) enables space-saving designs.
• Low quiescent current minimizes power consumption.

Disadvantages

• Limited reset timeout period may not be suitable for certain applications requiring longer timeouts.
• SOT23-5 package may be challenging to solder for inexperienced users.

Working Principles

The MAX6414UK35+T operates by continuously monitoring the supply voltage connected to the VCC pin. When the voltage drops below the selected threshold (determined by the TH pin), the RESET pin is asserted, providing a reset signal to the system. The manual reset input (MR) allows for an external reset control, overriding the voltage monitoring function.

Detailed Application Field Plans

The MAX6414UK35+T is commonly used in various applications where voltage monitoring and reset functionality are required. Some potential application fields include: 1. Battery-powered devices: Ensuring proper operation and preventing data loss when the battery voltage drops below a critical level. 2. Microcontroller systems: Providing a reliable reset signal during power-up or voltage fluctuations to ensure correct initialization. 3. Industrial automation: Monitoring power supply voltages in control systems to prevent malfunctions and ensure safe operation. 4. Automotive electronics: Resetting microcontrollers or other critical components when the vehicle's battery voltage falls outside the acceptable range.
