Diodes Incorporated APX803S-23SR-7 Voltage Supervisor IC

The APX803S-23SR-7 is a highly precise voltage supervisor component designed by Diodes Incorporated, a leading global manufacturer and supplier of high-quality semiconductor products. This micro-power, low-voltage detector is engineered to maintain system integrity by monitoring the supply voltage of microprocessors (MPUs), microcontrollers (MCUs), and other voltage-sensitive devices. It is an essential component for a wide range of electronic applications, from consumer electronics to automotive systems, ensuring reliable operation even under adverse conditions.

The device features a fixed threshold voltage of 2.3V, making it suitable for low-voltage applications. It is designed to assert a reset signal whenever the VCC voltage falls below the 2.3V threshold, keeping it asserted until the VCC voltage rises above the threshold, plus a minimum hysteresis. This ensures that the system has a stable supply voltage before resuming operation, thus preventing system errors or malfunction.

One of the key attributes of the APX803S-23SR-7 is its low supply current, which is typically 1µA, contributing to enhanced power efficiency in battery-operated devices. This feature is particularly important for portable and wearable technology where power conservation is critical.

The APX803S-23SR-7 comes in a compact SOT-23 package, which is ideal for space-constrained applications. It is also characterized by its fast response time, which is crucial for systems that require immediate reaction to voltage fluctuations. Additionally, the device is equipped with an active-low push-pull reset output, which provides a direct interface to the reset pin of the target microcontroller or processor without the need for external components.

Diodes Incorporated ensures that the APX803S-23SR-7 is compliant with RoHS and Green standards, reflecting the company's commitment to environmental responsibility. The device's operating temperature range from -40°C to +85°C allows for deployment in a variety of environments, further showcasing its versatility.

In summary, the APX803S-23SR-7 voltage supervisor IC from Diodes Incorporated is a reliable, efficient, and indispensable component for maintaining the correct operation of electronic systems by monitoring their power supply voltage. Its low power consumption, fast response time, and small footprint make it an excellent choice for designers looking to enhance system reliability without compromising on space or power efficiency.
