MAX16003ATE+

Supervisors Overview

The MAX16003ATE+ is a low-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features six monitored inputs with threshold voltages of 1.8 V, 2.5 V, 3.3 V, or adjustable settings. The device provides an active-low open-drain output and includes manual reset functionality alongside a watchdog timer. It operates within a supply voltage range up to 5.5 V, maintaining accuracy within 2.5%. The component supports a reset delay time of 200 ms and consumes 50 uA of operating current. It is housed in a TQFN-16 package and functions reliably across temperatures from -40 C to +125 C.

Supervisors Feature Summary

• Monitors up to six independent voltage rails for system integrity
• Integrates manual reset input and watchdog timer for fault recovery
• Provides active-low open-drain status output signaling

Supervisors Applications

• Multi-rail power supply monitoring in embedded systems
• Microprocessor reset generation in industrial controllers
• Watchdog timer implementation in safety-critical electronics

Supervisors Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct threshold voltage selection and feature set availability. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Ensure the TQFN-16 package compatibility matches your PCB footprint requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when simultaneous monitoring of multiple voltage rails is required without external comparators. The integrated watchdog and manual reset features reduce bill-of-materials complexity. Verify that the 5.5 V maximum supply rating aligns with your system's highest rail voltage. Consider the 200 ms reset delay duration relative to your processor startup timing requirements.

Supervisors Part Context

This part belongs to the MAX16003 series of quad-, hex-, and octal-voltage supervisors designed for low-power applications. It complements other Maxim Integrated supervisory circuits by offering multi-input monitoring capabilities in a compact surface-mount package. The series targets designs requiring robust power management and reliable reset generation for complex digital systems.

Supervisors Replacement Considerations

Consult official cross-reference lists for direct pin-compatible alternatives. Verify functional equivalence regarding input count, threshold options, and package dimensions before substitution.
