MAX6303CSA+T

Supervisors Overview

The MAX6303CSA+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of up to 5.5V and features an adjustable overvoltage threshold. The device provides an active-low, push-pull reset output with a manual reset input capability. It includes a watchdog timer function and has a typical reset delay time of 5.2 ms. The component draws 4 uA of operating supply current and functions reliably across a temperature range of 0°C to +70°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring alongside voltage supervision.
• Features an adjustable overvoltage threshold to accommodate various power rail requirements.
• Provides an active-low push-pull reset output for direct interface with digital logic.
• Includes a manual reset input pin allowing external control over the reset state.

Supervisors Applications

• Portable electronic devices requiring low-power voltage supervision
• Battery-operated systems needing efficient power management
• Microprocessor-based circuits requiring reliable reset generation

Supervisors Procurement Notes

Verify the specific suffix CSA+T indicates the SOIC-8 surface-mount package and tape-and-reel shipping format. Confirm the manufacturer designation as Analog Devices Inc./Maxim Integrated. Ensure the part status aligns with current availability constraints noted in distributor records. Cross-reference the RoHS compliance status if environmental regulations apply to your assembly process.

Supervisors Selection Notes

Select this component when an adjustable overvoltage threshold is required rather than a fixed undervoltage monitor. The integrated watchdog timer distinguishes it from basic supervisor ICs lacking this feature. Consider the 4 uA quiescent current for battery-sensitive designs. Verify that the SOIC-8 package fits the board layout constraints compared to other available packages in the MAX6303 series.

Supervisors Part Context

This part belongs to the MAX6303 series of low-power microprocessor supervisory circuits. The series is designed to monitor power supplies in portable applications where low current consumption is critical. The MAX6303 variant specifically offers adjustable thresholds and watchdog functionality, differentiating it from simpler reset generators in the broader Maxim Integrated portfolio.

Supervisors Replacement Considerations

Check for MAX6303 variants with different package options such as SOP or TSSOP if footprint changes are acceptable. Verify electrical compatibility regarding the 5.5V maximum supply and 4 uA current draw. Ensure the replacement supports the same active-low push-pull output configuration and manual reset input requirement.
