```

---

| | --|----|-- |____| | | |__| ```

1. VCC: Supply Voltage Input
2. GND: Ground
3. RESET: Reset Output
4. MR: Manual Reset Input

Functional Features

• Monitors supply voltage and provides a reset signal when it falls below the specified threshold.
• Reset output remains active until the supply voltage rises above the threshold and the reset timeout period elapses.
• Manual reset input allows for immediate system reset.
• Low quiescent current ensures minimal power consumption.

Advantages and Disadvantages

Advantages: - High accuracy voltage monitoring - Wide supply voltage range - Low power consumption - Small package size

Disadvantages: - Limited reset threshold options - Fixed reset timeout period

Working Principles

The MAX16057ATT41+T is a voltage supervisor IC that continuously monitors the supply voltage. When the voltage falls below the specified threshold, it asserts the reset output pin. The reset signal remains active until the supply voltage rises above the threshold and the reset timeout period elapses.

The manual reset input allows for an immediate system reset by asserting the reset output regardless of the supply voltage level.

Detailed Application Field Plans

The MAX16057ATT41+T is commonly used in various applications where reliable voltage monitoring is crucial. Some potential application fields include:

1. Battery-Powered Devices: Ensures proper shutdown or system reset when the battery voltage drops to critical levels.
2. Microcontroller Systems: Provides a reset signal during power-up and brownout conditions, ensuring stable operation.
3. Industrial Control Systems: Monitors power supply integrity, preventing data corruption or equipment malfunction during voltage fluctuations.
4. Automotive Electronics: Protects sensitive electronic components from damage due to voltage transients or sudden power loss.
