The APX803L05-44SA-7 is a highly precise voltage supervisor designed to ensure the reliable operation of microprocessor (µP) systems. Manufactured by Diodes Incorporated, this component is an essential piece in applications where voltage monitoring is critical for the system's performance and safety. The device is particularly suitable for battery-powered gadgets, portable electronics, and microprocessor-based systems that require a strict power supply regulation.

This voltage supervisor operates at a nominal threshold voltage of 4.4V, which makes it ideal for 5V systems. The APX803L05-44SA-7 features a low supply current of 10µA (typical), contributing to the overall power efficiency of the system it is integrated into. The device has a ±1.5% threshold accuracy over the entire operating temperature range of -40°C to +85°C, ensuring consistent performance even under varying environmental conditions.

One of the key characteristics of the APX803L05-44SA-7 is its active-low, push-pull reset output. This output remains asserted for a minimum of 240ms after the supply voltage has risen above the designated threshold, providing a reliable reset signal for the processor. This feature is crucial in preventing the system from starting up in an unstable state, thereby enhancing the overall system reliability.

The device comes in a small-footprint SOT-23 package, which is highly advantageous for space-constrained applications. Its small size, combined with the low power consumption, makes the APX803L05-44SA-7 an excellent choice for portable and compact electronic designs.

In summary, the APX803L05-44SA-7 from Diodes Incorporated is a versatile and reliable solution for voltage monitoring and system reset functions. Its precision, low power consumption, and compact form factor make it a valuable component for designers looking to enhance the operational stability of their electronic products.
