MAX6366HKA31+

Overview

The MAX6366HKA31+ is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of up to 5.5 V and features a threshold voltage of 3.08 V. The device provides one monitored input with an active high, open drain output type. It includes a manual reset capability and a watchdog timer function. The reset delay time is specified at 280 ms. The component supports battery backup switching and chip enable signals. It operates in temperatures from -40 C to +85 C and is housed in an SOT-23-8 package.

Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Includes manual reset functionality for user-initiated control
• Supports battery backup switching for power continuity
• Features chip enable signal for power management

Applications

• Microprocessor (uP) monitoring circuits
• Voltage supervision systems
• Battery backup switching applications

Procurement Notes

Verify the specific suffix 'HKA' against the official datasheet to confirm the exact threshold voltage and package variant, as suffixes define critical electrical parameters. Confirm availability status directly with the manufacturer or authorized distributors, as supply levels may vary. Ensure the operating temperature range meets the application requirements before procurement.

Selection Notes

Select this component when a supervisory circuit with both watchdog and manual reset capabilities is required. The 3.08 V threshold suits 3.3 V logic systems. Verify that the open drain output configuration aligns with the downstream logic interface. Consider the SOT-23-8 package size for space-constrained designs.

Part Context

This part belongs to the MAX6366P series of voltage supervisors. It is designed for microprocessor applications requiring comprehensive power management features including watchdog timers and manual resets. The series offers various threshold voltages and package options to suit different system architectures.

Replacement Considerations

Check for other MAX6366 variants with similar thresholds but different packages or reset types. Verify pin compatibility if substituting with other Maxim supervisor ICs. Ensure any replacement maintains the watchdog and manual reset functionality.
