ADM6328-27ARTZ-R7

Supervisors Overview

The ADM6328-27ARTZ-R7 is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring power supply voltages in embedded systems. It features a fixed voltage threshold of 2.7V and provides an active-low, open-drain reset output. The device operates within a supply voltage range up to 5.5V and supports manual reset functionality via an external input. Packaged in a compact SOT-23-3 surface-mount case, it ensures reliable system initialization and protection against brown-out conditions.

Supervisors Feature Summary

• Provides active-low reset signal with open-drain output configuration
• Includes manual reset input capability for system control
• Operates with ultra-low power consumption suitable for battery applications

Supervisors Applications

• Microprocessor and microcontroller power supply supervision
• Battery-powered portable electronic devices
• Industrial control systems requiring brown-out protection

Supervisors Procurement Notes

Verify the specific suffix ARTZ-R7 to confirm the tape-and-reel packaging format and temperature grade. Ensure compatibility with the target PCB footprint for the SOT-23-3 package. Confirm that the open-drain output architecture aligns with the pull-up requirements of the connected logic interface. Check RoHS compliance status if required by regional regulations.

Supervisors Selection Notes

Select this component when a fixed 2.7V threshold is required for low-voltage monitoring. The open-drain output necessitates an external pull-up resistor, which must be sized according to the bus capacitance and speed requirements. Consider the manual reset feature if hardware-initiated resets are needed during debugging or fault recovery scenarios.

Supervisors Part Context

This part belongs to the ADM6328 series of ultra-low power reset supervisors from Analog Devices. It shares functional similarities with the ADM6326 but differs in output type and specific threshold options. The series is designed for cost-sensitive applications requiring minimal component count and small footprint.

Supervisors Replacement Considerations

Direct substitutes include other ADM6328 variants with different voltage thresholds, such as ADM6328-29ARTZ-R7. Cross-reference with ADM6326 series parts if push-pull output is acceptable instead of open-drain.
