MAX6367PKA23+T

Overview

The MAX6367PKA23+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates with a supply voltage range of +1.2V to +5.5V and features a threshold voltage of 2.32V with an overvoltage threshold of 2.38V. The device monitors a single input and provides an active-low, open-drain output. Key functional elements include a battery backup switch, chip-enable gating with 1.5ns propagation delay, and a reset timeout period of at least 150ms. It draws a quiescent supply current of 10µA and is housed in an SOT-23-8 package.

Feature Summary

• Integrates battery-on output indicator for power source status monitoring
• Provides on-board gating of chip-enable signals with minimal propagation delay
• Ensures valid reset signals down to the minimum operating supply voltage of 1.2V

Applications

• Microprocessor system power-supply monitoring
• Battery-backup control functions
• Memory write protection circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm RoHS compliance details and specific lot traceability requirements before procurement. Ensure storage conditions align with manufacturer specifications to maintain integrity. Validate that the SOT-23-8 package variant matches design constraints. Review datasheet revisions for any updates regarding electrical characteristics or handling instructions prior to integration.

Selection Notes

Select this component when precise monitoring of 2.32V thresholds is required alongside battery backup indication. The open-drain output structure suits systems needing wired-OR configurations. Chip-enable gating simplifies logic design by reducing external components. Consider the 10µA quiescent current for battery-operated applications requiring extended standby life. Verify compatibility with the target system's minimum operating voltage of 1.2V.

Part Context

This part belongs to the MAX6365–MAX6367 series of supervisory circuits designed to simplify power management in embedded systems. Unlike the MAX6366 which includes a watchdog timer, the MAX6367 focuses on battery backup indication and chip-enable gating. It shares the low-power architecture and small SOT-23 footprint with other members of the family but offers distinct output features tailored for memory protection and power sequencing tasks.

Replacement Considerations

Cross-reference with MAX6367PKA23-V+T for automotive qualification if AEC-Q100 compliance is required. Verify pinout and electrical parameters against MAX6365 or MAX6366 variants if additional features like manual reset or watchdog timers are needed.
