```

---

| | --| VDD | --| /MR | --| GND | |_______| ```

Pin Descriptions: - VDD: Power supply input pin - /MR: Active-low reset output pin - GND: Ground reference pin

Functional Features

1. Voltage Monitoring: ADM6348-37ARTZ-R7 continuously monitors the voltage level at the VDD pin.
2. Reset Generation: When the voltage falls below the set threshold, the /MR pin is asserted low, generating a reset signal.
3. Adjustable Threshold: The reset threshold voltage can be adjusted within the range of 0.5V to 5.0V, providing flexibility in different applications.
4. Low Quiescent Current: The device operates with a low quiescent current of 10µA, minimizing power consumption.

Advantages and Disadvantages

Advantages

• Wide operating voltage range allows compatibility with various power supply systems.
• Adjustable reset threshold voltage provides adaptability to different voltage requirements.
• Small package size enables usage in space-constrained designs.
• Low quiescent current minimizes power consumption.

Disadvantages

• Limited reset threshold voltage range may not cater to all voltage monitoring needs.
• SOT-23-3 package may require additional handling precautions due to its small size.

Working Principles

ADM6348-37ARTZ-R7 works based on a voltage comparator circuit. It compares the voltage at the VDD pin with the internally set threshold voltage. If the voltage falls below the threshold, the /MR pin is pulled low, indicating a reset condition. Once the voltage rises above the threshold, the /MR pin returns to its high state.
