The SGM809 voltage supervisor, manufactured by SG MICRO, is a reliable solution for monitoring voltage levels in electronic circuits. As an authorized distributor, Supreme Components International offers this device, which features a single channel with an active-low, push-pull output configuration. The SGM809 is designed to assert a reset signal when the monitored voltage drops below a pre-determined threshold, ensuring system stability and preventing data corruption. Its compact SOT-23 package makes it suitable for space-constrained applications. This voltage supervisor is commonly used in microprocessors, microcontrollers, and other digital systems to provide a reliable reset function during power-up, power-down, or brownout conditions. The SGM809 offers a cost-effective and efficient way to enhance system reliability.
