```

---

| | --| VCC GND |-- Pin 1: Ground (GND) --| RESET OUT |-- Pin 2: Reset Output (RESET OUT) --| THRESHOLD |-- Pin 3: Threshold Voltage Input (THRESHOLD) --| MR/ |-- Pin 4: Manual Reset Input / Active-Low Reset Input (MR/) --| RESET |-- Pin 5: Power-On Reset Input (RESET) --| IN |-- Pin 6: Supply Voltage Input (IN) |___________| ```

Functional Features

• Monitors the supply voltage and generates a reset signal when it falls below the user-defined threshold.
• Provides a manual reset input for external reset control.
• Power-on reset input ensures proper system initialization.
• Adjustable threshold voltage allows customization for different applications.
• Low quiescent current minimizes power consumption.

Advantages

• Wide operating voltage range makes it suitable for various electronic systems.
• Small package size enables space-saving designs.
• Adjustable threshold voltage provides flexibility in voltage monitoring.
• Low-power consumption extends battery life in portable devices.
• Reset timeout period ensures reliable reset signals.

Disadvantages

• Fixed reset timeout period may not be suitable for all applications requiring longer or shorter timeouts.
• Limited number of threshold voltage options may not meet the requirements of all systems.

Working Principles

The MAX16058ATA26+T operates by continuously monitoring the supply voltage through the THRESHOLD pin. When the voltage drops below the user-defined threshold, the RESET OUT pin is asserted low, indicating a reset condition. The reset signal remains active until the supply voltage rises above the threshold and the reset timeout period elapses.
