The BD45421G-TR from ROHM Semiconductor is a voltage detector IC, also known as a supervisor IC. It is designed to monitor a single voltage supply, specifically at 4.2V, and generate a reset signal when the voltage drops below a critical threshold. The reset output is active low and has a minimum timeout period of 90ms.
This component operates within a temperature range of -40°C to 105°C (TA). It features an open drain or open collector output type. The BD45421G-TR is available in a compact 5-SSOP package, also identified as SC-74A or SOT-753, suitable for surface mounting.
Its primary function is to ensure system stability by preventing erroneous operations during power supply fluctuations. This makes it suitable for various embedded systems requiring reliable power monitoring and reset functionality.
