Technical Specifications

The RN5VL28AA-TL monitors the input voltage and asserts a reset signal when the voltage drops below the 2.8V threshold. The open-drain output allows for flexible interfacing with various logic levels, allowing it to be used in a wide range of applications. The low supply current minimizes power consumption, making it suitable for battery-powered devices. The small package makes it easy to integrate into space-constrained designs. The output is typically connected to a pull-up resistor to define the high-level voltage.
