Product Overview: APX803-29SAG-7 Microprocessor Reset Circuit

The APX803-29SAG-7 is a highly precise microprocessor reset circuit designed and manufactured by Diodes Incorporated. This compact and efficient component is engineered to monitor the supply voltage of microprocessors (μP) and digital systems, ensuring that a proper reset signal is delivered to the μP during power-up, power-down, and brown-out conditions. The inclusion of this device in a digital system enhances the reliability and stability of the overall operation, particularly in situations where power fluctuations are prevalent.

This device comes in a small SOT-23 package, making it suitable for space-constrained applications. The APX803-29SAG-7 boasts a fixed threshold voltage of 2.93V, which is meticulously designed to cater to the specific voltage requirements of various microprocessors and digital systems. When the supply voltage drops below this threshold, the reset output is activated, ensuring that the μP is held in a reset state until stable conditions are restored.

One of the key features of the APX803-29SAG-7 is its minimal power consumption, which is critical in portable and battery-operated devices. Its low supply current draw helps in prolonging battery life, making it an ideal choice for power-sensitive applications. Furthermore, the device offers a significant delay time of approximately 140ms (minimum), providing ample time for the system to stabilize before the μP is allowed to resume operation.

The APX803-29SAG-7 is designed with an open-drain output configuration, which allows for more flexibility in interfacing with different logic levels. It is also characterized by its ability to operate over a wide temperature range of -40°C to +105°C, ensuring functionality across diverse environmental conditions.

Applications for the APX803-29SAG-7 are broad and include consumer electronics, embedded systems, microcontroller boards, and any digital system that requires reliable voltage monitoring and reset capabilities. Its robust design and precise voltage threshold make it an essential component for maintaining the integrity of electronic systems.

Overall, the APX803-29SAG-7 from Diodes Incorporated is a testament to the company's commitment to providing high-quality, reliable components for the electronics industry. Its precise voltage monitoring and reset functionality are indispensable for the smooth operation of modern digital systems.
