Pin Configuration

The MAX16083AXR29E+T has a total of 5 pins:

1. GND: Ground connection.
2. MR: Manual reset input pin. When pulled low, it forces a reset regardless of the monitored voltage level.
3. RESET: Active-low reset output. It goes low when the monitored voltage falls below the threshold.
4. VCC: Power supply input.
5. TH: Threshold voltage selection pin. Connect to VCC or GND through a resistor to set the desired threshold voltage.

Functional Features

• Voltage Monitoring: Monitors the voltage level of the power supply continuously.
• Reset Generation: Generates an active-low reset signal when the voltage falls below the programmed threshold.
• Manual Reset: Allows for a manual reset by pulling the MR pin low.
• Adjustable Timeout Period: The reset timeout period can be adjusted to meet specific system requirements.
• Low Quiescent Current: Consumes minimal current during operation, ensuring power efficiency.

Advantages and Disadvantages

Advantages: - Compact and space-saving SOT23-5 package. - Wide supply voltage range allows for versatile applications. - Adjustable threshold voltage options provide flexibility. - Low quiescent current minimizes power consumption.

Disadvantages: - Limited reset timeout period range may not suit all applications. - Manual reset functionality may not be required in all systems.

Working Principles

The MAX16083AXR29E+T operates by continuously monitoring the voltage level of the power supply. When the voltage falls below the programmed threshold, the reset output goes low, indicating a reset condition. The reset signal remains active until the voltage rises above the threshold or a manual reset is triggered.

Application Field Plans

The MAX16083AXR29E+T finds applications in various electronic systems where reliable voltage monitoring and reset functionality are crucial. Some potential application fields include:

1. Microcontrollers and Microprocessors: Ensures proper initialization and safe operation during power-up and brownout conditions.
2. Industrial Control Systems: Protects sensitive equipment from voltage fluctuations and ensures stable operation.
3. Automotive Electronics: Provides reset capability to critical systems, such as engine control units (ECUs) and safety modules.
4. Battery-Powered Devices: Monitors battery voltage and triggers a reset when it drops below a certain level, preventing damage to the device.

Alternative Models

• MAX16084AXR29E+T: Similar to MAX16083AXR29E+T but with additional features like watchdog timer functionality.
• MAX16085AXR29E+T: Offers higher threshold voltage options for specific applications requiring different voltage levels.
