MAX6358TZUT+T

Overview

The MAX6358TZUT+T is a dual/triple-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors two input voltages and provides an active low, open-drain reset output with a manual reset feature. The device includes a watchdog timer and operates within a supply voltage range up to 5.5 V. It features threshold voltages of 1.8 V, 2.5 V, 3 V, 3.3 V, and 5 V, with overvoltage thresholds at 3.14 V and 4.46 V. The reset delay time is 280 ms, and the operating power current is 20 uA. It is housed in an SOT-23-6 package and functions between -40 C and +85 C.

Feature Summary

• Dual-input voltage supervision with configurable threshold options
• Integrated watchdog timer for system reliability monitoring
• Manual reset capability for user-initiated system recovery
• Low-power operation suitable for battery-supplied applications

Applications

• Portable electronic devices requiring multi-rail power monitoring
• Embedded systems needing watchdog functionality
• Industrial control units with multiple voltage domains
• Communication equipment requiring reliable reset sequencing

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices as availability may be limited. Ensure packaging specifications match project requirements before ordering.

Selection Notes

Select this part when dual voltage monitoring with watchdog support is required. Compare threshold options against system rail voltages. Consider package size constraints and operating temperature range compatibility with the target environment.

Part Context

Part of the MAX6358 series focusing on dual/triple voltage supervision. Shares family features like low quiescent current and manual reset but differs in specific threshold configurations and output types compared to other variants in the lineup.

Replacement Considerations

Check for pin-compatible alternatives within the same series. Verify functional equivalence regarding watchdog timeout periods and reset delay times before substitution.
