MAX6303ESA

Supervisors Overview

The MAX6303ESA is a low-power microprocessor supervisory circuit designed for +5V systems. It features an adjustable reset threshold voltage and includes a watchdog timer with manual reset capability. The device operates within a supply voltage range of 4.75 V to 5.25 V, consuming only 4 µA of quiescent current. It provides a push-pull active-low output and offers a fixed reset timeout delay of 2.8 ms minimum. The component is housed in an 8-pin SOIC package and supports industrial temperature ranges from -40°C to +85°C.

Supervisors Feature Summary

• Integrates adjustable power-supply monitoring with selectable threshold detection
• Includes built-in watchdog timer functionality with manual reset input
• Delivers robust system supervision through active-low push-pull output signaling

Supervisors Applications

• Safety-critical automotive electronic control units
• Industrial embedded systems requiring reliable power monitoring
• Consumer electronics utilizing standard +5V logic supplies

Supervisors Procurement Notes

Verify the specific suffix (e.g., ESA vs. CSA) against the official Analog Devices datasheet to confirm package type and temperature rating. Confirm RoHS compliance status via the manufacturer's current documentation. Ensure the selected variant matches the required operating temperature range for the target application environment before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a single-channel supervisory circuit with integrated watchdog functionality is required. The adjustable threshold allows customization for specific voltage tolerance needs. Consider the 4 µA power consumption for battery-sensitive designs. Verify that the 2.8 ms reset timeout meets the system startup timing requirements compared to other available options in the MAX6303 family.

Supervisors Part Context

This part belongs to the MAX6303 series of low-power supervisory circuits manufactured by Analog Devices/Maxim Integrated. The series focuses on providing essential power management protection for microprocessors and digital systems. The MAX6303ESA specifically denotes the SOIC-8 package variant suitable for surface-mount assembly in compact electronic designs requiring reliable voltage supervision.

Supervisors Replacement Considerations

Consult the official Analog Devices cross-reference guide for verified substitutes. The MAX6303CSA+T is a related variant with similar electrical characteristics but may differ in packaging or reel specifications. Ensure any replacement maintains the same active-low output polarity and watchdog functionality.
