MAX6307UK45D4-T

Supervisors Overview

The MAX6307UK45D4-T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It operates within a supply voltage range up to 5.5 V and features two monitored inputs with threshold voltages of 3.3 V and 5 V. The device provides an active low, open drain output type and includes a reset delay time of 1570 ms. It does not support manual reset or watchdog timers. The component functions within an operating temperature range of 0 C to +70 C and is housed in a SOT-23-5 package.

Supervisors Feature Summary

• Monitors multiple power supply inputs simultaneously for system integrity
• Provides active low open drain reset signal output
• Designed to ignore fast transients on monitored supplies

Supervisors Applications

• Personal computer systems monitoring 5V and 3.3V rails
• Portable applications requiring low supply current
• Microprocessor supervisory circuits

Supervisors Procurement Notes

Verify the specific suffix D4 against the manufacturer's official datasheet to confirm the exact threshold voltage configuration and pinout compatibility. Ensure the operating temperature range meets the application requirements as this variant specifies 0 C to +70 C. Cross-reference the package dimensions with the SOT-23-5 standard to ensure PCB footprint accuracy.

Supervisors Selection Notes

Select this component when simultaneous monitoring of two distinct voltage levels is required without manual reset functionality. The fixed thresholds simplify design compared to programmable variants. Consider the 1570 ms reset delay duration relative to system startup timing requirements. Verify that the open drain output interface matches the downstream logic input capabilities.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 family of 5-pin, multiple-input, programmable reset ICs manufactured by Maxim Integrated. These devices are specifically engineered for portable applications due to their low supply current consumption and small package size. The family allows for factory-programmed reset thresholds to accommodate various power supply standards.

Supervisors Replacement Considerations

Check for MAX6307UK45D2+T or MAX6307EUK44D2+T if lead-free compliance or different temperature ranges are needed. Verify electrical equivalence before substitution.
