Diodes Incorporated APX803S-26SA-7 Microprocessor Reset Circuit

The APX803S-26SA-7 is a highly reliable voltage monitoring and microprocessor supervisory circuit designed by Diodes Incorporated. This component is essential for systems that require precise voltage monitoring to ensure proper operation and protection against voltage fluctuations. The device is particularly suitable for battery-powered equipment, microcontrollers, and other electronic products where data integrity and system reliability are crucial.

With its compact SOT-23 packaging, the APX803S-26SA-7 is designed for space-constrained applications. It offers a fixed threshold voltage of 2.63V, which is ideal for 2.5V to 3.3V logic circuits. Upon detecting a voltage that falls below this threshold, the device generates a reset signal to the microprocessor, holding it in reset until the system voltage stabilizes. This reset signal is maintained for a minimum of 240ms after the supply voltage exceeds the threshold, ensuring the system has adequate time to recover.

The APX803S-26SA-7 features low power consumption, making it an energy-efficient choice for portable devices. Its high precision voltage threshold ensures that the device responds accurately to voltage changes, providing a reliable reset function. Additionally, the built-in hysteresis improves noise immunity and prevents false triggering from transient voltage fluctuations.

Key features of the APX803S-26SA-7 include:

• Fixed voltage threshold of 2.63V tailored for 2.5V to 3.3V logic circuits
• Low supply current ideal for battery-operated devices
• Minimum 240ms reset signal timeout
• High threshold accuracy and built-in hysteresis for reliable operation
• Compact SOT-23 packaging suitable for space-limited applications
• Operating temperature range from -40°C to +85°C

Applications for the APX803S-26SA-7 are diverse, encompassing consumer electronics, portable devices, computers, embedded systems, and any other systems that require a dependable reset mechanism to safeguard data and ensure consistent performance.

By integrating the APX803S-26SA-7 into your design, you can enhance system reliability and stability, protect against data corruption, and extend the lifespan of your electronic products. Diodes Incorporated's commitment to quality and performance is reflected in this efficient and precise voltage monitoring solution.
