MAX6368HKA29+

Overview

The MAX6368HKA29+ is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, housed in an SOT-23-8 package. It monitors a single input with a threshold voltage of 2.9 V and features an active high, open drain output. The device includes a chip enable signal and battery backup switch but lacks manual reset and watchdog timer functions. It operates within a supply voltage range up to 5.5 V, consumes 15 uA, and has a reset delay time of 280 ms. The adjustable overvoltage threshold supports flexible configuration. Operating temperatures range from -40 C to +85 C.

Feature Summary

• Integrates battery backup switching capability for seamless power transition monitoring
• Features chip enable gating for controlled operation states
• Provides active high open drain output signaling for system supervision

Applications

• Portable electronic devices requiring low-power voltage supervision
• Battery-operated systems needing backup power monitoring
• Embedded circuits utilizing chip-enable functionality

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices. Ensure the specific suffix matches design requirements as variations exist within the series. Validate datasheet revisions against current production batches to guarantee parameter accuracy.

Selection Notes

Select this component when a single-input supervisor with battery backup and chip enable is required. Compare threshold voltages against other MAX6368 variants to match specific rail levels. Consider the open-drain output compatibility with downstream logic levels. Evaluate power consumption constraints against the 15 uA operating current specification.

Part Context

This part belongs to the MAX6368P/H/L series of microprocessor supervisors. These devices are designed for low-voltage applications requiring reliable reset generation. The HKA29 variant specifically denotes the temperature grade and pinout configuration within the broader family of voltage monitoring ICs produced by Maxim Integrated.

Replacement Considerations

Check for MAX6368PKA29+ or MAX6367HKA29+T as potential functional equivalents within the same manufacturer portfolio. Verify pin compatibility and electrical parameters before substitution.
