Functional Features

• Precision Voltage Monitoring: The MAX16009TG+T accurately monitors the supply voltage and generates a reset signal when it falls below a user-defined threshold.
• Adjustable Thresholds: The threshold voltage can be set using an external resistor divider network, allowing flexibility in defining the desired voltage level for triggering the reset.
• Manual Reset Input: The MR pin allows for manual resetting of the device, overriding the automatic reset generation.
• Low Power Consumption: With a quiescent current of only 3µA, the MAX16009TG+T is designed for low-power applications, ensuring minimal power consumption.
• Reset Timeout Period: The device includes a reset timeout feature that ensures the reset output remains active for a specific duration after the supply voltage rises above the threshold.

Advantages and Disadvantages

Advantages: - Accurate voltage monitoring - Adjustable threshold levels - Low power consumption - Manual reset capability - Reset timeout feature

Disadvantages: - Limited to a 6-pin SOT23 package - Threshold accuracy may be affected by external factors such as temperature and component tolerances

Working Principles

The MAX16009TG+T operates by continuously monitoring the supply voltage at the TH pin. When the voltage falls below the user-defined threshold, the device generates an active-low reset signal on the RESET pin. The threshold voltage can be adjusted using an external resistor divider network connected to the TH pin. The MR pin allows for manual resetting of the device, overriding the automatic reset generation. The reset output remains active for a specific duration (reset timeout period) after the supply voltage rises above the threshold.

Detailed Application Field Plans

The MAX16009TG+T is commonly used in various applications where reliable voltage monitoring and reset generation are critical. Some potential application fields include:

1. Microcontrollers: Ensuring proper system initialization and preventing erratic behavior during power-up or brownout conditions.
2. Industrial Control Systems: Monitoring power supply voltages in industrial equipment to prevent damage or data corruption during voltage fluctuations.
3. Automotive Electronics: Providing voltage supervision in automotive systems to ensure safe operation and protect sensitive electronic components.
