• Threshold Voltage Range: 0.4V to VCC - 0.2V
• Quiescent Current: 3µA (typical)
• Operating Temperature Range: -40°C to +85°C

Pin Configuration

The MAX6364LUT23-T has a total of three pins:

1. GND: Ground pin
2. TH: Threshold input pin for setting the voltage threshold
3. RST: Reset output pin that goes low when the monitored voltage is outside the threshold range

Functional Features

• Adjustable Threshold: The threshold voltage can be set using an external resistor divider network connected to the TH pin.
• Precision Monitoring: The MAX6364LUT23-T provides accurate monitoring of the power supply voltage, ensuring reliable operation of the system.
• Low Power Consumption: With a quiescent current of only 3µA, the device minimizes power consumption, making it suitable for battery-powered applications.
• Reset Output: The RST pin provides an active-low reset signal when the monitored voltage falls outside the threshold range.

Advantages and Disadvantages

Advantages: - Adjustable threshold allows flexibility in voltage monitoring applications. - Low power consumption extends battery life in portable devices. - Small package size (SOT-23) enables space-saving designs.

Disadvantages: - Limited to monitoring voltage levels within the specified supply voltage range. - Requires an external resistor divider network for threshold adjustment.

Working Principles

The MAX6364LUT23-T operates by comparing the voltage at the TH pin with an internal reference voltage. When the monitored voltage exceeds or falls below the set threshold, the RST pin goes low, indicating a fault condition. The threshold voltage can be adjusted by connecting an external resistor divider network to the TH pin.
