Supervisors datasheet and documents for MAX803SEXR+T

MAX803SEXR+T

Supervisors Overview

The MAX803SEXR+T is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range up to 5.5 V and features a threshold voltage of 2.93 V with an overvoltage threshold of 2.96 V. The device provides an active low, open drain output and includes a reset delay time of 240 ms. It consumes 17 uA of operating current and maintains an accuracy of 1.5 %. The component supports surface mount installation in an SC-70-3 package and functions reliably across a temperature range from -40 C to +125 C.

Supervisors Feature Summary

Provides automatic microprocessor reset functionality upon power-up or voltage fault detection
Features an active low open drain output for direct interface with digital logic systems
Operates with ultra-low quiescent current consumption suitable for battery-powered applications

Supervisors Applications

Microprocessor reset circuits
Voltage monitoring in portable electronics
Battery backup systems supervision

Supervisors Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct threshold voltage and package type compatibility. Confirm RoHS compliance status through manufacturer documentation prior to integration. Check for end-of-life notifications or production discontinuation alerts from Analog Devices to mitigate supply chain risks during long-term design cycles.

Supervisors Selection Notes

Select this component when a fixed 2.93 V threshold is required for system supervision. Ensure the open drain output architecture aligns with the target pull-up requirements. Verify that the SC-70-3 footprint matches the PCB layout constraints. Consider the 240 ms reset delay duration relative to the processor startup timing requirements.

Supervisors Part Context

This part belongs to the MAX803S series of 3-pin microprocessor reset circuits. It is designed for simple voltage supervision tasks without manual reset inputs or watchdog timers. The series offers various threshold options differentiated by alphanumeric codes, with the 'SEX' indicating the specific 2.93 V threshold variant.
