MAX16155DDCD+T

Supervisors Overview

The MAX16155DDCD+T is a nanoPower supervisor and watchdog timer manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.2 V to 5.5 V, consuming only 400 nA of operating supply current. The device features a 1.5 V threshold voltage with 2.5% accuracy and provides an open-drain output. It includes a watchdog timer function and offers a reset delay time of 100 µs. Designed for surface mount installation in a SOT-23-6 package, it functions reliably across temperatures from -40°C to +125°C.

Supervisors Feature Summary

• Ultra-low power consumption suitable for battery-operated applications
• Integrated watchdog timer for system reliability monitoring
• High accuracy voltage supervision with fixed threshold
• Compact SOT-23-6 surface-mount packaging

Supervisors Applications

• Portable electronic devices requiring low standby current
• Industrial control systems needing watchdog functionality
• Automotive electronics operating in harsh temperature environments
• Battery-powered sensor nodes and IoT devices

Supervisors Procurement Notes

Verify the specific suffix DD indicates the tape-and-reel packaging configuration when ordering. Confirm that the +T designation aligns with your required reel quantity and handling specifications. Ensure compatibility with your assembly process regarding the SOT-23-6 footprint. Check for RoHS compliance documentation if required by your manufacturing standards. Validate availability through authorized distributors as stock levels may vary.

Supervisors Selection Notes

Select this component when a fixed 1.5 V reset threshold meets your system requirements. Choose the MAX16155DDCD+T over adjustable supervisors if simplicity and minimal external components are prioritized. Consider the 400 nA quiescent current for strict power budget constraints. Opt for the integrated watchdog feature if software fault detection is necessary without additional logic gates.

Supervisors Part Context

This part belongs to the MAX1615x series of nanoPower supervisors. It shares functional similarities with other models in the family but differs in specific threshold voltages and packaging options. The series is designed for applications demanding minimal power consumption and small form factors. Other variants may offer different thresholds or manual reset inputs.

Supervisors Replacement Considerations

Direct substitutes include other MAX16155 variants with compatible pinouts and electrical characteristics. Verify that alternative parts maintain the same 1.5 V threshold and open-drain output type. Ensure replacement components support the same operating temperature range and supply voltage limits.
