Maxim Integrated MAX6383XR23D3-T Microprocessor Reset Circuit

The MAX6383XR23D3-T is a highly reliable microprocessor (µP) supervisory circuit designed and manufactured by Maxim Integrated, a trusted name in the development of analog and mixed-signal products. This compact and efficient component is engineered to monitor power supplies in µP and digital systems, providing a robust solution for system monitoring and protection.

One of the key features of the MAX6383XR23D3-T is its ability to assert a reset signal whenever the VCC supply voltage falls below the factory-set reset threshold level. For this particular model, the reset threshold is precisely set at 2.3V. This ensures that the µP and other critical system components are reset properly, preventing any improper operation due to low voltage conditions.

The device boasts an impressive reset timeout period of 140ms (minimum), which provides sufficient time for the system to stabilize before normal operation is resumed. This timeout period is crucial for preventing the system from restarting prematurely during transient conditions or when power is being restored.

Another significant advantage of the MAX6383XR23D3-T is its tiny, space-saving SOT-323 package. With its small footprint, this component is ideal for use in space-constrained applications, such as portable devices, wearables, and IoT products, where board space is at a premium.

Additionally, the device features a low supply current of only 1µA (typical), making it an energy-efficient choice for battery-operated devices. Its low power consumption helps extend battery life, which is essential for mobile and portable applications.

For enhanced system reliability, the MAX6383XR23D3-T includes an active-low RESET output, which remains asserted for the duration of the reset timeout period after VCC has risen above the reset threshold. This output type is open-drain, allowing for the possibility of connecting multiple devices in a wired-OR configuration for more complex system monitoring.

Overall, the MAX6383XR23D3-T from Maxim Integrated is a robust and reliable solution for µP system monitoring, offering precise voltage monitoring, low power consumption, and a small package size, making it an excellent choice for a wide range of applications.
