Pin Configuration

The MAX16057ATT30+T has a total of six pins arranged as follows:

____ VCC | | GND NC | | RESET NC | | MR NC | | TH NC | | TRIP ----

• VCC: Power supply input pin
• GND: Ground reference pin
• RESET: Output pin that provides a reset signal when the monitored voltage falls below the threshold
• MR: Manual reset input pin for immediate system reset
• TH: Threshold adjustment pin to set the desired reset voltage threshold
• TRIP: Open-drain output pin that indicates when the monitored voltage is below the threshold

Functional Features

• Monitors power supply voltage and provides a reset signal when it falls below the set threshold
• Adjustable reset threshold allows customization for different system requirements
• Reset timeout period ensures that the reset signal is maintained for a specific duration after the voltage returns to normal
• Manual reset input allows for immediate system reset if required
• Open-drain output pin indicates when the monitored voltage is below the threshold, enabling external monitoring or control circuits

Advantages and Disadvantages

Advantages: - Low-power consumption makes it suitable for battery-powered applications - Wide operating voltage range allows compatibility with various power supply voltages - Adjustable reset threshold offers flexibility for different system voltage levels - Small package size saves board space in compact designs

Disadvantages: - Fixed reset timeout period may not be suitable for all applications requiring longer or shorter durations - Limited number of pins restricts the availability of additional features or functionalities

Working Principles

The MAX16057ATT30+T operates by continuously monitoring the power supply voltage connected to the VCC pin. When the voltage falls below the threshold set using the TH pin, the RESET pin is activated, providing a reset signal to the system. The reset signal remains active for the fixed timeout period, ensuring that the system is properly reset even if the voltage fluctuates momentarily. The TRIP pin can be used to externally monitor the voltage status.
