MAX6855UK23D4+T

Supervisors Overview

The MAX6855UK23D4+T is a single-channel voltage supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.6V to 5.5V and features a fixed reset threshold of 2.3V. The device provides an active-high, push-pull output with a manual reset input and no watchdog timer. Key electrical parameters include a maximum reset delay of 1.2s, a typical quiescent current of 7µA, and an overvoltage threshold of 2.36V. It is housed in a SOT-23-5 package and supports surface-mount installation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates voltage monitoring with a manual reset input for system control
• Provides an active-high push-pull reset output signal
• Features ultra-low supply current consumption for power efficiency

Supervisors Applications

• Microprocessor power supply supervision
• Battery-powered portable electronics
• Embedded system voltage monitoring

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices, as this part may be subject to limited availability or discontinuation. Ensure the specific suffix matches required pinout and electrical characteristics before integration into design.

Supervisors Selection Notes

Select this component when a fixed 2.3V threshold and active-high output are required. Compare against similar models like the MAX6855UK24D4+T if a 2.4V threshold is needed. Consider the MAX6855UK23D3+T variant if an open-drain output is preferred instead of push-pull. Verify that the 7µA current draw meets low-power design constraints.

Supervisors Part Context

This part belongs to the MAX6854/MAX6855 series of nanopower microprocessor supervisory circuits. These devices combine voltage monitoring, manual reset, and optional watchdog functions in a compact five-pin SOT23 package. The series is designed for applications requiring reliable power management with minimal standby current consumption.

Supervisors Replacement Considerations

Direct substitutes include MAX6855UK23D3+T (open-drain output) and MAX6855UK24D4+T (2.4V threshold). Cross-reference datasheet specifications for output type and threshold voltage compatibility before substitution.
