MAX16002DTC+T

Supervisors Overview

The MAX16002DTC+T is a low-voltage, quad-voltage microprocessor supervisor circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors four independent voltage rails and provides reset signals via an active-low, open-drain output. The device features a fixed reset timeout of 140 ms and operates within a supply voltage range up to 5.5 V. It is housed in a compact 12-pin TQFN package with exposed pad (4x4 mm) for surface-mount installation. The component supports manual reset functionality and includes a watchdog timer for system reliability. It operates across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Monitors four independent voltage inputs simultaneously
• Provides active-low open-drain reset output
• Includes integrated watchdog timer functionality
• Supports manual reset input for system control

Supervisors Applications

• Multi-rail power supply monitoring in embedded systems
• Microprocessor reset generation in industrial controllers
• Voltage supervision in portable electronic devices
• System integrity monitoring in automotive electronics

Supervisors Procurement Notes

Verify the exact suffix DTC+T against the manufacturer's current datasheet to confirm pinout and electrical specifications. Confirm RoHS compliance status as required by your assembly process. Check for obsolescence notices or lifecycle changes directly with Analog Devices. Ensure the TQFN-12-EP package footprint matches your PCB design guidelines. Validate that the 140 ms reset timeout meets your system's startup requirements.

Supervisors Selection Notes

Select this component when simultaneous monitoring of four distinct voltage rails is required. The open-drain output allows for wired-OR configuration with other supervisors. The wide operating temperature range suits harsh environments. Consider the 140 ms timeout duration relative to your system's power-up sequence. Verify that the 5.5 V maximum supply voltage aligns with your highest monitored rail.

Supervisors Part Context

This part belongs to the MAX16002 family of low-voltage supervisors designed for multi-rail applications. It shares functional similarities with other Maxim Integrated supervisors but is distinguished by its four-channel monitoring capability and specific package form factor. The family targets cost-sensitive designs requiring robust power management without complex external components.

Supervisors Replacement Considerations

Direct substitutes include other MAX16002 variants with different suffixes indicating package or temperature variations. Cross-reference pinouts carefully when substituting with similar quad-supervisors from other manufacturers. Ensure equivalent reset timeout and threshold accuracy if system timing is critical.
