MAX6360TWUT+T

Overview

The MAX6360TWUT+T is a dual/triple-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range up to 5.5V and features overvoltage thresholds of 1.7V and 3.14V. The device monitors multiple power supplies, asserting reset outputs if any input drops below preset levels. It includes a debounced manual reset input and a watchdog timer with specific startup and timeout periods. The component supports active-low push-pull outputs referenced to VCC1 or VCC2, depending on the variant configuration, and functions reliably across an extended temperature range from -40°C to +85°C.

Feature Summary

• Monitors multiple power-supply voltages including +1.8V, +2.5V, +3.0V, +3.3V, and +5V options
• Includes a watchdog timer with extended startup timeout period
• Features a debounced manual-reset input compatible with TTL/CMOS logic
• Provides precision factory-set power-supply reset thresholds for improved system reliability

Applications

• Microprocessor system power supervision
• Multi-voltage embedded controller monitoring
• Industrial control systems requiring extended temperature operation

Procurement Notes

Verify current availability status as this component may be subject to limited supply or end-of-life restrictions. Confirm package type and pinout compatibility during integration. Ensure that the specific threshold voltages match the target power rails. Check for RoHS compliance documentation. Validate that the watchdog timer requirements align with system timing constraints before finalizing procurement decisions.

Selection Notes

Select this component when simultaneous monitoring of two or three distinct voltage rails is required. Consider the MAX6360 series variants based on whether active-low push-pull outputs are needed versus open-drain configurations. Evaluate the need for a watchdog timer feature against simpler supervisor alternatives. Ensure the operating temperature range meets environmental specifications. Verify that the manual reset input debounce characteristics suit the application's noise environment.

Part Context

The MAX6360 belongs to the Maxim Integrated MAX6351–MAX6360 family of microprocessor supervisors. This series replaces discrete components to enhance accuracy and reduce board space. The MAX6360 specifically offers triple-voltage monitoring capabilities with configurable reset outputs. It shares common features like low supply current and extended temperature ranges with its siblings in the MAX635x series.

Replacement Considerations

Direct substitutes include other MAX635x series devices such as MAX6358 or MAX6359, provided they meet the specific voltage threshold and output configuration requirements. Cross-reference pinouts and electrical characteristics carefully. Verify that alternative parts support the same watchdog timer functionality if required.
