MAX6366PKA44-T

Overview

The MAX6366PKA44-T is a voltage supervisory circuit from the MAX6366P series, manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range up to 5.5 V and features a threshold voltage of 4.40 V. The device provides an active low, open-drain output with a reset delay time of 280 ms. Key functional blocks include a watchdog timer, battery backup switch, and chip enable gating. It consumes 15 uA of operating current and detects overvoltage at 4.75 V. The component is housed in an SOT-23-8 package and supports surface mount installation across a temperature range of -40 C to +85 C.

Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Includes a battery backup switch for power transition management
• Features chip enable gating for power control flexibility

Applications

• Microprocessor supervision in embedded systems
• Battery-powered device power management
• Industrial control system monitoring

Procurement Notes

Verify the specific suffix 'T' indicates reel packaging when sourcing. Confirm availability status as distribution channels may list limited stock or end-of-life conditions. Ensure the manufacturer designation matches Analog Devices / Maxim Integrated to guarantee authenticity. Cross-reference the exact part number against official datasheets to confirm pinout and electrical specifications before procurement.

Selection Notes

Select this component when a 4.40 V threshold is required for single-input voltage supervision. Consider the integrated watchdog and battery backup features if system resilience during power fluctuations is critical. Verify that the SOT-23-8 package fits the design constraints and that the active low open-drain output aligns with the target logic interface requirements.

Part Context

This part belongs to the MAX6366P family of low-power microprocessor supervisors. These devices are designed to monitor voltage levels and provide reset signals to ensure proper system operation. The MAX6366P series distinguishes itself by combining voltage supervision with additional features like watchdog timers and chip enable controls in a compact form factor suitable for space-constrained applications.

Replacement Considerations

Consult official substitution guides for compatible parts within the MAX6366P series. Verify equivalent threshold voltages and package compatibility before replacing.
