Introducing the APX803L20-42SA-7 Voltage Supervisor from Diodes Incorporated

The APX803L20-42SA-7 is a highly precise voltage supervisor designed to maintain system integrity by monitoring the power supply voltage levels in digital systems. Manufactured by Diodes Incorporated, a leading global manufacturer and supplier of high-quality application-specific standard products within the broad discrete, logic, analog, and mixed-signal semiconductor markets, this voltage supervisor ensures that your electronic systems operate within their specified voltage range, safeguarding them against unpredictable power fluctuations that could lead to system failures.

This particular model, the APX803L20-42SA-7, comes in a compact SOT-23 package, making it ideal for space-constrained applications. It boasts a low supply current, which is beneficial for battery-operated devices, ensuring minimal power consumption and extended battery life. With a factory-trimmed threshold voltage of 4.2V, it provides the precision necessary for reliable operation in sensitive electronic equipment.

The device features a built-in delay time of 20ms, which prevents false triggering due to transient conditions, thereby enhancing system stability. Upon detecting a voltage that is below the threshold, the APX803L20-42SA-7 asserts a reset signal to the host processor, which remains asserted until the system voltage has stabilized above the threshold for a continuous period set by the internal timer.

One of the key attributes of the APX803L20-42SA-7 is its ability to support a wide operating temperature range of -40°C to +85°C, allowing it to perform reliably in various environmental conditions. This makes it suitable for use in industrial, automotive, and consumer electronics that may be exposed to harsh temperatures.

Furthermore, the APX803L20-42SA-7 is RoHS compliant and lead-free, reflecting Diodes Incorporated's commitment to environmental sustainability while providing a product that meets current industry standards for health and safety.

Whether you are designing power management systems, microcontroller monitoring, or portable electronics, the APX803L20-42SA-7 from Diodes Incorporated is an excellent choice for a voltage supervisor that combines precision, reliability, and energy efficiency.
