ON Semiconductor CAT810STBI-GT3 Voltage Supervisor

The CAT810STBI-GT3 is a high-performance voltage supervisor device designed by ON Semiconductor, a leading provider of semiconductor-based solutions. This precision voltage supervisor is engineered to maintain system integrity by monitoring the supply voltage of digital systems and providing a reset signal to the host processor when necessary.

The CAT810STBI-GT3 is particularly suitable for portable and battery-powered applications due to its low power consumption and compact SOT-23 package. Its main role is to ensure that the microprocessor, microcontroller, or other digital systems reset correctly during power-up, power-down, or a brown-out condition. The device's active-low reset output remains asserted until the system voltage reaches the reset threshold level and maintains stability for the reset active time.

Key features of the CAT810STBI-GT3 include:

• Precision monitoring of 3V, 3.3V, and 5V supply voltages.
• 140 ms minimum reset pulse width which ensures proper system reset.
• Low supply current of 5 µA (typical) suitable for battery-operated equipment.
• Operating temperature range from -40°C to +85°C, accommodating a wide range of environmental conditions.
• Immunity to short V_CC transients, providing reliable operation under fluctuating power conditions.

The CAT810STBI-GT3 is designed with an open-drain output, which allows for the connection of multiple devices to a common reset line. This feature simplifies the design of systems requiring voltage monitoring on multiple rails. Additionally, the device's built-in glitch immunity ensures that the output remains in a non-asserted state during brief dips in the supply voltage, thus avoiding unnecessary system resets.

In summary, the ON Semiconductor CAT810STBI-GT3 voltage supervisor is an essential component for any system requiring reliable operation and robust protection against power supply inconsistencies. Its precision voltage monitoring and reset capabilities make it an ideal choice for a variety of applications, including portable devices, computers, embedded systems, and many other electronic products.
