The APX810-23SAG-7 is a highly reliable, precision microprocessor (μP) supervisory circuit designed to maintain system integrity during power failures or unexpected brownout conditions. Manufactured by Diodes Incorporated, this component is a crucial safeguard for microprocessor systems, ensuring that the processor and associated hardware are reset to a known, stable state in the event of a power supply glitch.

This device operates by monitoring the VCC voltage and keeping the microprocessor in reset until that voltage reaches the factory-programmed reset threshold level. Once VCC is above the threshold, the APX810-23SAG-7 keeps the processor in an active reset state for a minimum of 140ms (typical) after VCC has risen above the reset threshold, providing ample time for the system to stabilize.

The APX810-23SAG-7 comes in a space-saving SOT-23 package, making it ideal for use in systems where board space is at a premium. Its low supply current of 10μA (typical) is particularly beneficial for portable battery-operated equipment. With an operating temperature range of -40°C to +85°C, this device is versatile enough to be used in a wide variety of operating environments.

Key features include:

• Precision monitoring of 3.3V power supplies
• 140ms minimum reset pulse width
• Low supply current of 10μA (typ.)
• Factory-trimmed reset threshold for high accuracy
• Immune to short VCC transients
• Operating temperature range: -40°C to +85°C
• RoHS compliant and lead-free

The APX810-23SAG-7 is an essential component for any system that requires reliable operation and protection against data corruption due to volatile power supply conditions. Its precision and low power consumption make it an excellent choice for managing microprocessor reset functions in a variety of applications, from consumer electronics to industrial control systems.
