MAX6367PKA46+T

Overview

The MAX6367PKA46+T is a uPower Supervisor circuit manufactured by Analog Devices / Maxim Integrated. It operates within a supply voltage range of up to 5.5 V and features a threshold voltage of 4.63 V with an overvoltage threshold of 4.75 V. The device draws a typical operating current of 15 uA and provides a reset delay time of 280 ms. It utilizes an SOT-23-8 package for surface mount installation. The output type is active low push-pull, supporting battery backup functionality. It lacks manual reset and watchdog timer capabilities. The component functions across a temperature range from -40 C to +85 C.

Feature Summary

• Integrates chip enable gating for power management control
• Supports battery backup switching for continuous monitoring
• Provides active low push-pull reset output signal

Applications

• Microprocessor system supervision
• Battery-powered portable devices
• Embedded controller voltage monitoring

Procurement Notes

Verify the exact suffix KA46 against official datasheets to confirm the specific threshold voltage variant. Confirm RoHS compliance status through manufacturer documentation. Check current availability as distribution channels may indicate limited stock or discontinuation. Ensure the SOT-23-8 package matches your PCB footprint requirements before ordering.

Selection Notes

Select this component when low quiescent current is critical for battery life. The integrated chip enable feature allows external control of the supervisor state. Verify that the 4.63 V threshold aligns with the monitored rail voltage. Consider the push-pull output drive capability for direct interfacing with logic inputs without additional pull-up resistors.

Part Context

This part belongs to the MAX6367L series of uPower Supervisors designed for low-power applications. It shares functional similarities with other Maxim Integrated supervisors but offers specific threshold and packaging options. The series emphasizes minimal power consumption while maintaining reliable reset generation for sensitive digital circuits in compact form factors.

Replacement Considerations

Consult official cross-reference guides for verified substitutes. Ensure replacement parts match the SOT-23-8 package and 4.63 V threshold. Verify compatibility with chip enable and battery backup features if required by the design.
