Introducing the APX810S-26SA-7 Voltage Supervisor IC

The APX810S-26SA-7 is a highly precise microprocessor (μP) supervisory circuit designed by Diodes Incorporated to maintain system integrity during power-up, power-down, and brown-out conditions. This compact integrated circuit (IC) is essential for applications that require reliable operation and protection against unpredictable voltage fluctuations.

At the heart of the APX810S-26SA-7 is a voltage monitor that guards the system's power supply. It ensures that the voltage level remains within a safe threshold, and if a drop is detected, it generates a reset signal to the connected microprocessor. This reset signal maintains a valid logic level until the supply voltage stabilizes above the preset threshold, plus a delay time to guarantee a proper system reset.

Key Features

• Precision Monitoring: With a factory-trimmed threshold voltage of 2.63V, it provides high-accuracy voltage monitoring, ideal for sensitive electronic systems.
• Low Power Consumption: The APX810S-26SA-7 is designed for power-sensitive applications, consuming minimal power and thus preserving battery life in portable devices.
• Manual Reset Capability: It includes a manual reset input, permitting users or external circuits to initiate a system reset whenever necessary.
• Reset Timeout: The device features a 140ms minimum reset timeout duration, ensuring that the system has adequate time to recover after a power disturbance.
• Temperature Range: It operates over a wide temperature range from -40°C to +85°C, suitable for industrial and automotive environments.

Applications

The APX810S-26SA-7 is versatile and can be used in a variety of applications, including:

• Microprocessor and Microcontroller Systems
• Portable/Battery-Powered Equipment
• Embedded Control Systems
• Intelligent Instruments
• Automotive Electronics

Enclosed in a small SOT-23 package, the APX810S-26SA-7 is designed for space-constrained applications. Its small footprint, combined with its robust feature set, makes it an excellent choice for designers looking to enhance system reliability without sacrificing board space.

Diodes Incorporated's commitment to high-quality and performance is evident in the APX810S-26SA-7, making it a dependable component for safeguarding electronic systems against voltage anomalies.
