Working Principles

The MAX6388XS34D4-T is designed to monitor the supply voltage of electronic systems. It compares the input voltage with a reference voltage and asserts the reset output when the voltage falls below the set threshold. The reset remains active until the voltage rises above the threshold or a manual reset signal is applied.

The device operates with low quiescent current, minimizing power consumption. It is housed in a small SC70 package, making it suitable for space-constrained applications.

Detailed Application Field Plans

The MAX6388XS34D4-T can be used in various applications, including:

1. Battery-powered devices: Provides voltage monitoring and reset functionality to prevent erratic behavior or data corruption when the battery voltage drops.
2. Microcontroller systems: Ensures reliable system operation by resetting the microcontroller when the supply voltage falls below a certain level.
3. Industrial control systems: Monitors power supply voltage in industrial equipment to prevent malfunctions or damage caused by voltage fluctuations.
