Additional Details:

The RH5VL28AA-TR features a detection voltage of 2.8V. The operating temperature ranges from -40°C to +85°C. It typically comes in a SOT-23 or similar small surface-mount package. The device outputs a low signal when the voltage drops below the detection threshold and goes high when the voltage recovers above the threshold. Proper external components, such as a pull-up resistor, are required due to its open-drain output configuration. Its low supply current is a key advantage in power sensitive applications.
