MAX6302CSA+

Supervisors Overview

The MAX6302CSA+ is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for monitoring power supply voltages in microprocessor systems. It operates within a voltage range of 1.5V to 5.5V and features an adjustable reset threshold voltage selectable via external resistors. The device provides a single channel with an open-drain or open-collector output that can be configured for active-high or active-low reset signals. It includes a programmable watchdog timer with a timeout period ranging from 140ms to 70s, ensuring system reliability. The component is available in an 8-SOIC surface-mount package and supports an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Configurable watchdog timer with selectable timeout periods for enhanced system fault detection
• Adjustable reset threshold voltage allowing flexibility in various power supply monitoring applications
• Open-drain/open-collector output architecture supporting both active-high and active-low configurations

Supervisors Applications

• Microprocessor system supervision
• Portable equipment power management
• Battery-powered consumer electronics

Supervisors Procurement Notes

Verify the specific suffix 'CSA+' against the official Maxim Integrated datasheet to confirm the commercial temperature grade (-40°C to +85°C) and SOIC-8 package variant. Ensure compatibility with your board's thermal requirements and voltage thresholds before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a low-cost supervisory circuit with a built-in watchdog timer is required. It is suitable for designs needing adjustable reset thresholds rather than fixed internal references. Consider the open-drain output capability if interfacing with different logic voltage levels is necessary.

Supervisors Part Context

This part belongs to the MAX630x series of low-power microprocessor supervisory circuits. It shares functional similarities with other members like the MAX6301 and MAX6304 but offers specific watchdog and threshold adjustment features distinct to its family classification within Analog Devices' power management portfolio.

Supervisors Replacement Considerations

Direct substitutes include the MAX6302CUA+ (uMAX/uSOP package) or MAX6302ESA+ (SOIC-8 package). Verify pinout compatibility and electrical specifications before swapping packages.
