MAX16001CTE+

Supervisors Overview

The MAX16001CTE+ is a low-voltage, quad-input microprocessor supervisor circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors four independent voltage rails and provides reset signals via an active-low, open-drain output. The device features a manual reset input and an integrated watchdog timer for system reliability. Key electrical parameters include a maximum supply voltage of 5.5 V, a quiescent current of 50 uA, and a reset delay time of 280 ms. Threshold voltages are fixed at 1.8 V and 2.5 V, with corresponding overvoltage thresholds of 1.71 V and 2.375 V. It operates within a temperature range of -40 C to +125 C and is housed in a TQFN-16 package.

Supervisors Feature Summary

• Monitors four independent voltage inputs simultaneously for comprehensive power rail supervision.
• Integrates a watchdog timer to detect software faults and ensure system stability.
• Includes a manual reset input allowing external control over the reset state.
• Delivers reset signals through an active-low, open-drain output interface.

Supervisors Applications

• Multi-rail power monitoring in embedded systems
• Microprocessor reset generation in industrial controllers
• Watchdog protection in communication equipment

Supervisors Procurement Notes

Verify component authenticity due to discontinued status. Confirm lot codes and date codes against manufacturer records. Check for RoHS compliance documentation. Ensure storage conditions meet humidity sensitivity levels. Validate pinout compatibility with target PCB footprint before integration.

Supervisors Selection Notes

Select this part when fixed threshold voltages of 1.8 V and 2.5 V match system requirements. Consider the 280 ms reset delay for timing constraints. Evaluate the TQFN-16 package for thermal and space limitations. Compare against adjustable variants if custom thresholds are needed.

Supervisors Part Context

Part of the MAX16001 family of low-voltage supervisors. Shares core functionality with other suffixes like ETE+ and BTE+, differing primarily in threshold voltage configurations and accuracy specifications. Designed for compact surface-mount applications requiring multi-channel power monitoring.

Supervisors Replacement Considerations

MAX16001ETE+ offers adjustable thresholds. MAX16001BTE+ provides alternative fixed thresholds including 3.3 V. Verify pinout and functional equivalence before substitution.
