The R5486K504CM-TR is a voltage detector IC manufactured by Ricoh. Voltage detectors, also known as voltage supervisors or reset ICs, monitor the input voltage of a system and generate a reset signal when the voltage falls below a certain threshold. This ensures that the system starts up correctly and prevents malfunction due to undervoltage conditions.

Technical Specifications

The R5486K504CM-TR features a detection voltage of 5.0V. It also likely incorporates an adjustable delay circuit (check the datasheet for specifics). The supply current is very low, typically in the microampere range. The package is a small surface-mount type, such as SOT-23 or similar, which facilitates automated assembly. Hysteresis is often included to prevent oscillations near the threshold voltage. The operating temperature range typically spans from -40°C to +85°C. The output type is often open-drain or CMOS.
