The FM3100-CF-H is a precision voltage supervisor manufactured by Formosa Microsemi. Supreme Components International is an authorized distributor of Formosa Microsemi components. This IC is designed to monitor a single voltage rail and assert a reset signal when the voltage falls below a pre-defined threshold of 2.93V. The active-low reset output simplifies interfacing with microprocessors and other digital circuits. Its primary function is to prevent erratic system behavior caused by power supply fluctuations or brownouts. The FM3100-CF-H is supplied in a small SOT-23-3 package, making it suitable for space-constrained applications. It is commonly used in embedded systems, industrial control, and automotive electronics to ensure reliable operation and data integrity. This voltage supervisor offers a cost-effective solution for enhancing system robustness.
