Product Overview: APX810S-23SA-7

The APX810S-23SA-7 is a robust microprocessor supervisory circuit designed by Diodes Incorporated, a leading manufacturer and supplier of high-quality semiconductor products. This component is engineered to monitor the power supply voltage in microprocessor systems, providing a significant layer of protection by ensuring that all system voltages are within operational limits.

At the heart of the APX810S-23SA-7 is its ability to assert a reset signal whenever the VCC supply voltage drops below a preset threshold, 2.3V in this case. This reset signal is maintained for a minimum of 240ms after VCC has risen above the reset threshold, ensuring that the system has adequate time to stabilize before resuming operation. This feature is critical in preventing system errors and data corruption during power-up, power-down, and brown-out conditions.

The device comes in a space-saving SOT-23 package, making it an ideal choice for use in compact systems where board space is at a premium. The APX810S-23SA-7 is characterized for operation over the temperature range of -40°C to +85°C, offering reliable performance across a wide range of environmental conditions.

Key features of the APX810S-23SA-7 include:

• Precision monitoring of 2.3V power supplies
• Low supply current of 10µA (typical), which is highly beneficial for power-sensitive applications
• Reset pulse width of 240ms (minimum) ensures proper system reset
• Immunity to short VCC transients
• RoHS-compliant and lead-free, adhering to environmental standards

Applications for the APX810S-23SA-7 are diverse and include:

• Microprocessor / Microcontroller systems
• Computers and laptops
• Portable / Battery-powered equipment
• Intelligent instruments
• Industrial controllers

With its precise voltage monitoring and reliable reset functionality, the APX810S-23SA-7 from Diodes Incorporated is an essential component for designers looking to enhance system reliability and protect against the consequences of unpredictable power supply fluctuations.
