MAX6366HKA46+T

Overview

The MAX6366HKA46+T is a uPower supervisory circuit manufactured by Analog Devices / Maxim Integrated. It monitors a single voltage input and provides an active-high reset signal via an open-drain output. The device features a fixed threshold voltage of 4.63 V and a typical reset delay time of 280 ms. It operates within a supply voltage range up to 5.5 V and consumes only 15 µA of quiescent current. The component is housed in an SOT-23-8 surface-mount package and supports battery backup switching functionality.

Feature Summary

• Provides low-power voltage supervision with minimal current consumption for extended battery life
• Features an open-drain active-high reset output compatible with various logic families
• Includes battery backup switching capability to maintain system integrity during power transitions

Applications

• Portable electronic devices requiring efficient power monitoring
• Battery-operated systems needing backup switching protection
• Embedded microprocessor reset circuits in industrial environments

Procurement Notes

Verify the exact suffix and manufacturer documentation, as this component is listed as discontinued or having limited availability from major distributors. Confirm RoHS compliance status through official datasheets before integration. Ensure the specific batch matches the required operating temperature range of -40°C to +85°C for your application environment.

Selection Notes

Select this part when a fixed 4.63 V threshold is required for single-input monitoring. It is suitable for designs prioritizing ultra-low standby current over adjustable thresholds. Consider the open-drain output requirement for pull-up resistor implementation. Verify that the SOT-23-8 package fits the PCB layout constraints compared to alternative supervisory ICs.

Part Context

This component belongs to the MAX6368H/MAX6366 series of uPower supervisors designed for low-voltage applications. It shares functional similarities with other Maxim integrated circuits but is distinguished by its specific 4.63 V threshold and active-high configuration. The series targets portable electronics where power efficiency and compact packaging are critical design parameters.
