MAX793TESE+T

Supervisors Overview

The MAX793TESE+T is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed for microprocessor supervision applications. It operates within a supply voltage range up to 5.5 V and features adjustable threshold voltages of 3.0 V and 3.3 V. The device integrates a watchdog timer, manual reset capability, and a battery backup switch. It provides active high, active low, and open drain outputs with a fixed reset delay time of 280 ms. The component supports chip enable functionality and consumes a typical operating supply current of 62 uA. It is housed in a SOIC-Narrow-16 package and functions reliably across an industrial temperature range from -40 C to +85 C.

Supervisors Procurement Notes

Verify the exact suffix against official Analog Devices documentation to confirm pinout and electrical characteristics, as variations exist within the MAX793 family. Confirm availability status directly with authorized distributors, as supply constraints may apply. Ensure the selected variant matches the required package type and temperature rating for your specific design environment before finalizing procurement.

Supervisors Selection Notes

Select this component when a supervisory circuit with integrated watchdog and manual reset is required. Compare the 62 uA quiescent current against system power budgets. Verify that the 280 ms reset delay aligns with processor startup timing requirements. Ensure the SOIC-Narrow-16 package fits the PCB layout constraints and that the 5.5 V maximum input voltage covers the system's peak supply levels.

Supervisors Part Context

The MAX793 series belongs to Analog Devices' portfolio of supervisory circuits designed for reliable system management. This specific part number represents a variant within the MAX793R family, characterized by its combination of voltage supervision, watchdog functionality, and manual reset control. It serves as a critical component for ensuring stable operation in digital systems requiring precise power monitoring.

Supervisors Replacement Considerations

Consult official cross-reference data for direct substitutes. Verify compatibility of threshold voltages, output drive capabilities, and package dimensions. Ensure any replacement maintains the same watchdog timeout behavior and reset delay specifications to preserve system integrity without redesigning the surrounding circuitry.
