Introducing the APX810-46SRG-7 Voltage Supervisor IC from Diodes Incorporated

The APX810-46SRG-7 is a highly reliable, precision microprocessor (μP) supervisory circuit that provides an essential protective measure for ensuring the integrity of system operations. Manufactured by Diodes Incorporated, a leading company in the semiconductor market, this voltage supervisor IC is designed to monitor the system voltage in digital systems and microprocessor-based applications.

With its fixed factory-programmed threshold voltage of 4.6V, the APX810-46SRG-7 is perfect for managing power supplies and ensuring that systems are operating within their safe voltage limits. This threshold accuracy is maintained over a wide temperature range, making it suitable for a variety of challenging environments.

The device features a reset output, which remains asserted for a minimum of 240ms after the system voltage exceeds the reset threshold level. This reset delay provides ample time for the system to stabilize before the microprocessor boots, thus preventing erroneous system operation. The APX810-46SRG-7 is active high and comes in a compact SOT-23 package, which is ideal for space-constrained applications.

Key features of the APX810-46SRG-7 include:

• Precision Monitoring: With a threshold voltage of 4.6V, the device provides accurate voltage supervision for 5V systems.
• Low Power Consumption: The IC is designed for efficiency, drawing minimal quiescent current, which is essential for battery-operated devices.
• Wide Operating Temperature Range: The device can operate over a temperature range of -40°C to +85°C, making it versatile for various applications.
• Power-On Reset Pulse: It generates a guaranteed reset pulse when the supply voltage becomes higher than the reset threshold.
• Compact Packaging: The small SOT-23 package is suitable for use in space-sensitive designs.

The APX810-46SRG-7 is an ideal choice for applications that demand high reliability and accuracy in voltage monitoring, such as portable devices, embedded systems, and other digital equipment that require a stable and reliable operation. Its low power consumption and small form factor also make it an excellent choice for power-sensitive applications.

With the APX810-46SRG-7, designers can ensure their systems are protected against the consequences of undervoltage conditions, thereby enhancing the performance and longevity of their products.
