Introducing the APX810-40SAG-7 Voltage Supervisor from Diodes Incorporated

The APX810-40SAG-7 is a highly reliable, precision microprocessor (μP) supervisory circuit designed by Diodes Incorporated to monitor the power supply voltage of digital systems. It ensures that the system's voltage remains within operational limits, safeguarding the system against unpredictable behavior in the event of power fluctuations.

This voltage supervisor is particularly adept at managing system resets by issuing a reset signal whenever the V_CC supply voltage drops below the preset threshold of 4.0V. The reset signal is maintained for a minimum of 140ms after V_CC has risen above the reset threshold level, ensuring that the system has ample time to stabilize before normal operation resumes. This feature is essential for systems that require a reliable startup and operational stability.

The APX810-40SAG-7 comes in a compact SOT-23 package, which is ideal for space-constrained applications. It has a wide operating voltage range, making it suitable for various digital systems, including microcontrollers, microprocessors, and other voltage-sensitive components.

Key features of the APX810-40SAG-7 include:

• Precision monitoring of 4.0V power supplies
• 140ms minimum reset pulse width
• Low supply current of 10μA (typical)
• Wide operating voltage range
• Guaranteed reset output down to V_CC = 1.0V
• Temperature range of -40°C to +85°C
• RoHS compliant and halogen-free

This voltage supervisor is designed for a variety of applications, including computers, controllers, intelligent instruments, portable/battery-powered electronics, and other critical microprocessor or microcontroller power monitoring scenarios. Its robust design ensures that it can withstand harsh conditions while providing the necessary protection to your electronic systems.

With its precision voltage monitoring and reset capabilities, the APX810-40SAG-7 from Diodes Incorporated is the go-to solution for designers looking to enhance the reliability and performance of their digital systems.
