Diodes Incorporated APX803L40-18SA-7 Voltage Supervisor IC

The APX803L40-18SA-7 is a highly precise voltage supervisor IC designed 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 compact, micro-power component is essential for monitoring the voltage level of power supplies in digital systems, ensuring that the system operates optimally within its power specifications.

With a fixed threshold voltage of 4.0V, the APX803L40-18SA-7 is tailored for applications that require a precise voltage monitoring solution. The device provides a significant level of protection for your electronics by asserting a reset signal whenever the monitored voltage drops below the threshold. It keeps the reset signal active until the voltage level recovers and stabilizes, thereby preventing system malfunction or damage due to an unexpected power dip or outage.

The APX803L40-18SA-7 comes in a compact SOT-23 package, making it suitable for space-constrained applications. It offers a reset delay time of 18ms, which is ideal for avoiding false triggers due to transient voltage fluctuations. This feature is particularly beneficial in complex electronic systems where stability and reliability are paramount.

Key features of the APX803L40-18SA-7 include:

• 4.0V fixed threshold voltage for accurate sensing
• Low supply current, making it suitable for battery-powered applications
• Guaranteed reset output down to Vcc = 1.0V
• Power supply transient immunity
• Operating temperature range from -40°C to +85°C
• RoHS compliant and lead-free, ensuring environmental sustainability

This voltage supervisor IC is widely used in microcontrollers, computers, data storage devices, and other intelligent electronic systems that require consistent monitoring and management of power supply conditions. Its robust design and reliable performance make the APX803L40-18SA-7 an excellent choice for safeguarding your critical applications against power-related issues.

For designers and engineers looking for a dependable voltage monitoring solution, the APX803L40-18SA-7 from Diodes Incorporated offers the perfect blend of precision, power efficiency, and compactness to meet the rigorous demands of modern electronic systems.
