Pin Configuration

The MAX708TCSA+T has the following pin configuration:

```

---

| | --| VCC | --| GND | --| RESET | --| MR | --| RESET OUT | |___________| ```

• VCC: Power supply input
• GND: Ground reference
• RESET: Active-low reset input
• MR: Manual reset input
• RESET OUT: Reset output

Functional Features

• Monitors the power supply voltage continuously
• Provides a reset signal when the voltage falls below the preset threshold
• Adjustable reset threshold and timeout period options
• Low quiescent current for power efficiency
• Active-low reset input allows external reset control
• Manual reset input for immediate system reset

Advantages

• Precise voltage monitoring ensures reliable system operation
• Adjustable threshold and timeout options provide flexibility for different applications
• Low quiescent current minimizes power consumption
• Small SMT package allows for space-saving designs
• Manual reset input offers additional control over system reset

Disadvantages

• Limited to voltage monitoring and reset functionality, not suitable for complex power management tasks
• Requires external components for proper operation
• Not suitable for high-voltage applications

Working Principles

The MAX708TCSA+T operates by continuously monitoring the power supply voltage. When the voltage falls below the preset threshold, it generates a reset signal. The reset signal remains active until the voltage rises above the threshold or the timeout period elapses. The device also provides an active-low reset input for external reset control and a manual reset input for immediate system reset.
