```

---

| | --| VCC | --| /RESET| --| GND | |_______| ```

Pin Description: - VCC: Power supply input pin. - /RESET: Active-low reset output pin. - GND: Ground reference pin.

Functional Features

1. Voltage Monitoring: MAX824LEUK+T continuously monitors the voltage level at the VCC pin.
2. Reset Signal Generation: When the voltage falls below the set threshold, it generates an active-low reset signal at the /RESET pin.
3. Adjustable Threshold: The reset threshold voltage can be adjusted using external resistors connected to the VCC and /RESET pins.
4. Power-On Reset Delay: It provides a power-on reset delay of typically 140ms to ensure stable operation during power-up.

Advantages and Disadvantages

Advantages

• Compact size and low power consumption make it suitable for portable and battery-powered devices.
• Wide operating voltage range allows compatibility with various electronic circuits.
• Adjustable reset threshold provides flexibility in different applications.
• Power-on reset delay ensures reliable system initialization.

Disadvantages

• Limited number of pins may restrict its use in complex systems requiring multiple functionalities.
• Lack of built-in hysteresis may result in potential noise-related issues.

Working Principles

MAX824LEUK+T operates by comparing the voltage at the VCC pin with the internally set threshold voltage. When the voltage falls below this threshold, the /RESET pin is pulled low, indicating a reset condition. The reset signal remains active until the voltage rises above the threshold again.

Application Field Plans

MAX824LEUK+T finds applications in various fields, including: 1. Battery-powered devices: It ensures proper voltage monitoring and system reset in portable electronics like smartphones, tablets, and wearables. 2.
