ON Semiconductor MAX810SQ293D2T1G Voltage Supervisor

The MAX810SQ293D2T1G is a precision microprocessor (μP) supervisory circuit designed by ON Semiconductor to monitor power supplies in digital systems. It provides a significant level of system reliability and accuracy required by modern electronic applications. This voltage supervisor ensures that the system's microprocessor is reset to a known state during power-up, power-down, or brown-out conditions.

Key Features

• Voltage Threshold: The device features a preset threshold voltage of 2.93V, which is suitable for monitoring 3.3V power supplies.
• Reset Output: The MAX810SQ293D2T1G provides an active-low reset signal. This signal remains asserted until the VCC voltage exceeds the reset threshold and maintains for a reset timeout period, ensuring a proper system reset.
• Power-On Reset Delay: The reset output is guaranteed to remain in the active state for a minimum of 140ms after VCC has risen above the reset threshold voltage. This delay provides stability and gives the system adequate time to stabilize.
• Low Power Consumption: Designed for low power consumption, the device is an ideal choice for portable and battery-powered applications.
• Temperature Range: The voltage supervisor operates over a wide temperature range, making it suitable for various environments and applications.
• Compact Package: It is available in a small outline package (SOT-23), which is ideal for space-constrained applications.

Applications

The MAX810SQ293D2T1G is versatile and can be used in a variety of applications that require voltage supervision, including:

• Computers and Controllers
• Intelligent Instruments
• Portable/Battery-Powered Equipment
• Embedded Systems
• Automotive Systems

With its precise voltage monitoring and reliable reset functionality, the MAX810SQ293D2T1G from ON Semiconductor is a crucial component for ensuring the proper operation and stability of electronic systems. Its integration into a design can help prevent system failures and data corruption by providing a robust power management solution.
