Overview
The MAX6345ZUT is a fixed voltage supervisor IC from Maxim Integrated, designed for monitoring single power supply rails. It operates within a supply voltage range of 1.2V to 5.5V and features a precise threshold of 2.33V. The device includes a manual reset input and an open-drain active-low reset output. It is housed in a compact SOT-23-6 package, suitable for surface-mount applications requiring reliable power management.
Feature Summary
- Monitors a single power supply voltage with a fixed threshold
- Includes a manual reset input for system control
- Provides an open-drain active-low reset signal
- Operates across a wide supply voltage range
Applications
- Microprocessor reset circuits
- Battery-powered systems
- Portable electronics
- Embedded controller supervision
Procurement Notes
Verify the exact part number suffix, as variants like MAX6345ZUT+T indicate specific packaging or tape-and-reel configurations. Confirm that the 2.33V threshold matches the target application requirements. Ensure the SOT-23-6 footprint aligns with the PCB design. Check for automotive grade specifications if operating in harsh environments.
Selection Notes
Select this component when a fixed 2.33V threshold is required for a single rail. Consider the manual reset pin if external reset control is needed. The SOT-23-6 package offers space efficiency. Verify compatibility with the system's operating voltage range of 1.2V to 5.5V before integration.
Part Context
This part belongs to the MAX6345 family of voltage supervisors. It shares functional similarities with other Maxim reset ICs but is distinguished by its fixed 2.33V threshold and manual reset capability. It serves as a simple solution for power-on reset generation in low-voltage digital systems.
Replacement Considerations
Direct substitutes include other Maxim voltage supervisors with similar thresholds and packages. Verify electrical parameters such as threshold accuracy and reset delay times. Ensure the replacement supports the same manual reset functionality and open-drain output configuration.
