MAX6307UK45D2+T

Supervisors Overview

The MAX6307UK45D2+T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features an active-low, open-drain reset output and supports a supply voltage range of 1 V to 5.5 V. The device monitors two inputs with fixed threshold voltages of 3.3 V and 5 V. It operates within a temperature range of -40°C to +85°C and consumes 8 µA of operating supply current. The reset delay time is specified at 1.4 ms.

Supervisors Feature Summary

• Monitors up to two independent power supply inputs simultaneously
• Provides an active-low, open-drain reset signal for system control
• Operates with low quiescent current consumption suitable for battery applications

Supervisors Applications

• Multi-rail embedded systems requiring simultaneous voltage supervision
• Industrial equipment monitoring critical power rails
• Telecommunications infrastructure power management

Supervisors Procurement Notes

Verify the suffix D2 indicates specific factory-set thresholds. Confirm RoHS compliance status as indicated by the plus sign. Ensure the package matches SOT-23-5 requirements. Check lead availability due to potential lifecycle changes in legacy Maxim products.

Supervisors Selection Notes

Select this part when dual-input supervision is required without programmable thresholds. Compare against MAX6307 variants with different fixed thresholds if standard voltages do not match the design. Consider the open-drain output requirement for pull-up resistor implementation.

Supervisors Part Context

Part of the MAX6305–MAX6313 family of supervisory circuits. Designed for applications needing reliable reset generation from multiple power sources. Manufactured by Analog Devices Inc./Maxim Integrated using CMOS technology for low power operation.

Supervisors Replacement Considerations

Check MAX6307EUK45D2+T for lead-free version compatibility. Verify MAX6307UK45D4-T if extended temperature range or different packaging is needed.
