The FM3100-A-Q1-H is a precision voltage supervisor manufactured by FORMOSA MICROSEMI. Supreme Components International is an authorised distributor of FORMOSA MICROSEMI components. This single-channel voltage supervisor is designed to monitor voltage levels and provide a reset signal when the voltage falls below a pre-set threshold. The adjustable threshold feature allows for customization to specific application requirements. The active low reset output ensures a clear indication of undervoltage conditions. Housed in a compact SOT-23-5 package, the FM3100-A-Q1-H is suitable for space-constrained applications. It is commonly used in microcontrollers, memory systems, and other critical electronic circuits to prevent data corruption and system malfunctions caused by voltage drops. Its reliable performance and small size make it an excellent choice for a wide range of voltage monitoring applications.
