Single Channel Supervisor IC, SOT‑23
Stock Quantity: 0
The APX809S05-31SA-7 is a single-channel voltage supervisor integrated circuit (IC) manufactured by DIODES INCORPORATED. This device monitors voltage levels and provides a reset signal when the voltage falls below a specified threshold. It is housed in a compact SOT-23 package, making it suitable for space-constrained applications requiring reliable voltage monitoring.
This voltage supervisor is commonly used to safeguard microcontrollers, microprocessors, and other digital systems from undervoltage conditions. It ensures proper system initialization and prevents erratic operation due to voltage drops. Its small size and low power consumption make it ideal for portable and embedded systems.
